Well after further research I have found out that the Gigabyte G1975X does not support SLI, which was something that i was for sure going to do later in my computers life span.

Since my number 1 choice of Mobo's is out of the question, can anybody suggest a good mobo for 100-200$ (US)? I am not very informed about mobos. I find it hard to keep on the for front of the technologies...
 
I can only guess at the speed/performance ratio for an Arctic Cooling Freezer 7, as I've never used one. I would assume that the 80mm fan and 2 heatpipes would be inferior to the Gigabyte G-Power with 120mm fan and 3 heatpipes, but its only a guess.

As mentioned, its not necessary to run the CPU @ 4.1GHz. Obviously, as speed increases, so does heat. At 3.6GHz we run the 805 @ stock voltages with the Gigabyte all the way down and get 60C under full load.

@ 3.8 (1.4v, fan still all the way down) it idles at 45C and gets to 66C under full load. The systems that we sell will be set to 3.8GHz for this reason, and will include the G-Power. It runs fine at 4.0GHz with the fan half way up, but I figure better safe than sorry. 🙂

You should never see 80C on the CPU if your motherboard supports/has enabled the CPU thermal control. Both our CPUs begin to throttle back at 72C. This should help to increase the life of the CPU, but how long this CPU lasts overclocked remains to be seen. We're going this route because I can buy 2 of these for every 1 830D, and frankly the 805 performs better.

Also, because the system bus is running so high, your memory will perform better than it does with your 630 OC. You'll lose hyper-threading, but gain dual core. Haven't seen where giving up hyper-threading is an issue so far.

If it were me, I'd go for it. But you may need to upgrade the CPU cooler if it proves to be inadequate. 🙂

Currently only NF4 supports SLI. Word is that NF5 will be out in the next couple months. Some 975x boards (including the Gigabyte G1975X) support Dual PCI-E Graphics at x16, but not the same thing. Intel put out the word a few months ago that their new 975x would support SLI, but it hasn't happened yet. The Asus P5WD2-E Premium supports Dual PCI-E Graphics x16 or CrossFire Mode at x8.

So your choices are NF4 for SLI (many currently under $200USD, probably no support for Conroe), or 975x for dual graphics and/or CrossFire (none under $200USD, but possible support for Conroe), or wait for NF5 to be released (doubt they'll be any immediatly available under $200USD, SLI, Intel CPU, and supports Conroe or so they say).

The Gigabyte GA-8NSLI ROYAL is a good board for SLI, Intel CPU, and under $200USD. 🙂
 
Don't know if this helps, but i replaced my 571J (3.80) with the 805 and even clocked at 3.6 it blows away my old 3.8 that was oced to just under 4.0. I don't think anyone uses Aquamark anymore, but I went from a 79,800 to a 94,600. I play alot of Bf2 and there is a very noticeable difference. Anyway at 130 bucks it make a nice tide me over till the Concore is out. You don't have to go all the way up to 4.1. I think between 3.4 -3.8 would be a good compromise.

I think there was something wrong with your old setup, in aquamark your old cpu @ 3.9ghz should have beat the d805.A 15000 point difference is suspect benchmarks should be about the same clock for clock until maybe 3dmark06 where you would see around 800point difference only in the cpu score because of the dual core.
Much less a "very noticeable difference". even if you play at a screen size of 800*600

You know maybe I have just been out of the scene of buying and researching parts for too long, but it seems that the PCI-E mobos like Gigabyte GA-8NSLI ROYAL are very skimpy on extra PCI slots. All I could install on this thing would be a nice sound card and possibly an additional NIC. Is this just how things are trending now adays? Just use the onboard features and use the two PCI slots for out of the ordinary devices?

BTW DarkLife41 thanks for all of your help! I really appreciate all input everyone has given on this whole subject. It is making me more and more comfortable about buying this setup and trying the overclocking!

Its all good. 🙂

With the new onboard (8 Channel) sound, a sound card is a waste of $ IMO. I've heard the talk about sound cards being crisper on good speakers, but I'm not buying it. I run a 500w Creative Cambridge soundworks 5.1 surround system (rattles the windows and wakes the neighbors) and notice no difference between the onboard and an Audigy 4 or even X-Fi Elite. Have to say that I'm not real impressed with Asus's Realtek HD Audio, as I'm getting feedback that I've never gotten before at anything over half volume. But Gigabyte onboard sound rocks. My computer has replaced our $5000 home stereo for the past several years using onboard sound. I play sports and racing games and watch the occasional movie on it as well.

Its true that PCI slots are becoming scarce. However with all the USB slots, 1394, sound, and dual LAN already provided on the I/O, the only thing I've used a PCI slot for in the past couple years is a modem (backup, just in case the ADSL2 goes down) and video capture card. Most anything else I need (removable HD bay, sound/video editing, etc) is better when set up in a 5.25 bay. Usually have a PCI slot or 2 that never gets used anyway. 🙂
 
I'll be able to give a report on the performance of the Arctic Cooling Freezer 7 as I bought it for my setup. In benchies, it was within 1 degree of the Thermaltake Big Typhoon at 1/2 the price. I decided to try a fan mod, putting a Silverstone FM121 on it (variable fan up to 110 cfm) with the extra money and see how it would perform at different fan speeds.

I just received the last of my buildout kit this morning, so when I get out of the office in 4 hours I'll start working on it.

Benchies to follow 😀

Yeah a sound card and a NIC but its ok everything else will be moving to PCI-E slots soon as well hmmm although I think you will see one PCI slot on almost all mobo's for years to come. I have already seen some PCI-E RAID controllers so thats a good thing :)
 
Thanks darklife41 for all the info. My rule of thumb so far is to OC as far as I can and stay under 60C so the CPU is still going to have a long life. I am glad to hear at 3.6 it is still under 60C underload, I have a case I modded myself with 2 80mm fans (both suck in air, one directly over my video card and other one over the ram, then the CPU fan sucks the air off the ram, cools the CPU, then goes out the back to a third fan out the case) and then of course my dual fan PSU. Heat has never been an issue for me with a 600mhz OC on air for the CPU and my 7800GTX oced as well.

I'll be glad to hear the result of the Arctic Cooling Freezer 7 on the 805 from you DexMan. To see the heat my CPU can get to I run an encoding with windows media encoder 9, upscale the video and put decoder complexity to complex, solid 100% for around 15 mins to see true load heat. If that program knows how to use dual core I would reccomend that.

And btw, I bought the CPU last night before all this. Just looking over everyone elses success, and the fact my CPU is 168 on newegg I will sell my current one and hopefully make only a small payment to upgrade, really depends on what I get for it on ebay. I should get it monday. Only problem is I have noe floppy drive at the moment and I need to upgrade my BIOS before I install it, lol. Floppy drives seem to last me only half a year. Again, thanks for all the info and I look forward to those results Dexman.
 
Just wanted to let anyone out there who is curious about weather this overclock actually works for regular people that yes, it does work! So far I'm quite satisfied with my new system's performance. I'm running completely stable, all the games I have installed and tried look and run great! F.E.A.R. is fabulous on this system! Another question I knew I had when I started looking into this overclock was how well it worked on an nForce4 SLI board, I hadn't really seen anyone talking about using anything other than Intel boards. Well my ASUS P5N32-SLI Deluxe has been great, and I didn't have to throw away my 7900 GT, and get an ATI card just to use the Pentium D.
However, one thing I would suggest, is not to get an Antec P180 under any circumstance! For such a large heavy case, it's surprisingly cramped to work inside of, and the logistics of routing cables are a total frustration! It's as if Antec had a whole bunch of great idea's about how to revolutionize the PC enclosure industry, and then decided to implement them completely wrong. I kept finding myself saying "Hey, that's a great idea...if only it actually worked!" as I was putting this system together. Everything else from Antec that I own is a top quality product. Just stay away from the P 180! It looks pretty nice though...of course every time I look at it I get flash backs of the nightmare it was to install the hardware inside. Oh, and it's not really that quiet either.

Well there are 2 ways to test a CPU, stress and heat, I mean, I think thats the two things that everyone looks at when OCing a CPU. For heat, I found that using some sort of video encoder is the best becaue it stays a near solid 100%. I use Windows Media Encoder 9, and I take some long video, tell it to double the resolution (just to make sure it doesnt finish soon) and set the decoder complexity to complex. I let it run from 10-20 min, thats about how long it takes until I see the temp no longer rise.

As for stress, technically the above would work too but people like to use burn in tests that programs use that are designed to stress like sandra and do it for hours and hours. I usually only test for heat because I try to keep my heat below 60C which never allows the CPU to really reach a speed that would cause instabilty, My mobo adjusts voltage on its own but I have to go manual if I really want to go high. I only forced my ram to run at 333 (666mhz) because my ASUS would immediately start dropping my ram speed. Other than that, I just test the heat and play games, I don't test for stability, just game, if I can game then I am happy.

Oh and my cpu MIGHT be here today, not sure, its shipping only 2 hours away from where I live sooooooo yea, fingers crossed.
 
oh and also, what kind of cooling are you using for the 805
Click to expand...

I am using an Innovatek System. Consists of an Eihem pump, header tank, res, and their large twin fan radiator; controled by their usb controler. HighSpeed Pc carries them and they are great to deal with. I do nothing but work maybe Sunday I can get those readings.

You are probably right I had reload windows before I could get stable over clocking. The memory speeds were changed and the graphics card was also over-clocked. These were not included when I ran the 571 mark. So, it may be kinda bogus comparison. On 3dMark05 running the 805 at 3.4 I got a cpu score of 5722 and 5515 running the 571 at 3.99. At the time the 571 was running on a Xp 64, so again prob bogus, but I thought interesting. The 805's score at 3.4 seems low compared to Tom's score at 3.32.
 
Ok first results:

Stock voltage @ 3.6 - 180 FSB =

42c @ IDLE
52c @ FULL LOAD


Is that a good start for hitting 3.9 / 4.1 ?
 
I dunno I'm no expert, but that's better than what I'm getting with a wc system. I am about 58c under full load. I can run at 3.8, but my scores are lower than at 3.6 prob because the chip is throttling down. Not sure if I have a weak ocing chip or if it the link between the computer and keyboard (me). At 3.8 at .14 volts the chip hits about 64c, usally, if the temp goes to any higher I usally crash.
I am going to keep the chip at 3.6 and read more on this voodoo science. At 3.6 the temps are low and the performance is acceptable.
 
ye mines watercooled.

I've managed to get my IDE temp down to 35 .... gonna run a new test now .. stand by.

*. ... Full load now 47 c ....


sweet.
 
I keep seeing people mention they're temps with water cooled. Would the Zalman 9500 be able to keep the CPU down under 65C? Thats saying the case has good enough cooling as well. I've been thinking of possibly setting up a special rig of my own where an intake fan is attached to a hose and blows cool air from the outside directly to the CPU. Would this be advised or does that decrease the cooling efficiency of the HSF?

Also is it better to have more exaust or more intake fans or the same of both? Im looking to have atleast two intake in the front, one exhaust in back and one up top. Also thinking about a fan on the side....
 
Well I have 2 intakes on the side, one directly to the video card and the other to the ram and CPU fan. The CPU takes that air, pushes it over the HS and then it meets an out fan like 2 inchs later, my PSU is also has 2 outs. So when I get the CPU Monday, I will be able to give you a good idea how air cooling does with, what I think, is good air flow. I live in the Mojave desert and its summer time, so my results will be worst case scenario, hehe.

Also, anyone here know how I could overide my fans on my PSU? They change speed depending on heat and hardly spin even when I am gaming, I tried using SpeedFan but couldnt get it to alter the speed, any ideas?
 
Can someone please answer a few question i have about this processor.

My first question is about purchasing the right processor. I have been told that you have to purchase the Intel Pentium D Processor 805 that has the proper product code. If you look at this link here it has the last 5 code #s circled.

spec_sticker.jpg


Now Ive been looking at Mwave's and Neweggs websites and the product code ends after the BX80551PE2666FN. I dont see the SL8ZH listed anywhere and have tried calling with no help. Has anyone bought one of these from MWAVE or NEWEGG recently that can verify if the product code once you have the processor box reads BX80551PE2666FNSL8ZH. Or is this a big myth?

2nd

Would this mother board support this processor and would it have any problems with overclocking?

I just recently setup an OC 805 system, got lucky and they sent me an x1900xt while charging me 270euros for a x1800xt 512!

I have an older, coolermaster hyper "something" huge copper heatsink with 120fan. The system is stable at fsb170 (3.4ghz) (idle 46C, load 60C) but wont boot at 180.
I recently bought a 550w jsp psu (see thru with lights and crap) for $50 and I'm afraid it might be the culprit. Also, I hooked up the x1900xt to an hdd type power connector w/adaptor because the PSU didn't have a PCIe connector. I also get this strange phenonenon where my UPS beeps everytime the gpu runs on full load (spellforce2 or bf2 full detail). Normally it only beeps when the power goes out. BTW, the psu has a fan knob, is it dangerous to leave it on mid to low or will the psu fry everything? thing is so noisy at full blast.

finally I have more of a noob problem with my motherboard, asus p5wd2-premium. I can't get the PRI EIDE cable to work.. I hook up two different hdd's and it sees nothing bt my two SATA ones, only driver I found on the CD is marvel RAID... the eide controler is identified as from marvel as well (in the manual) but I don't want RAID.

Anyway, this has the result of forcing me to use my windows PATA Hdd while sharing the controller with the DVDR as master.. ie, load times crawl, in bf2 I have to walk through the level once with the hard disk chugging and killing the frame rate no after that it's smooth as butter...(my p3 400 w/RIVA TNT used to do that on UT 1999; the more things change, the more they stay the same).
I'm waiting for a new case to change the hdd to master (cable lenghts) but what about that other controller?

any help ironing out these last niggles (did I mention Im broke) will be appreciated, I imagine some other noobs might have similar problems.
