Either 3dmark05/06 and CPUz 1.33.1 don't support the 975 chipset, or I have a bad CPU as only 1 core is listed and benchmarking.

My problems have been traced to either the CPU or motherboard, as the dual core should be showing in CPUz and also doesn't work correctly in Sisoft Sandra '07 Business edition. So the project continues... 🙂
 
... But $300 is way too much for a setup that doesn't include any blocks.

What block do you primarily use? I'm planning on getting a Swiftech Storm. Heard a lot of good things about it.

I can't speak for prices in the USA since I bought mine in Australia. I paid over $800AUD for all the components and am happy as can be with it.

Since my system also serves as a display model for our customers, I wanted the system to match and look good. My current system is all Koolance components. CPU-305-V10 (CPU), pair of GPU-VID-NV2-L06 (6800 Video cards), and GPU-180-V06 (chipset). Currently cooling the CPU, 1 GPU as the other BFG card fried within a month, and the chipset.

The Storm performs best with a high pressure pump. Make sure you have at least 1 GPM flow. Yuck @ 1/4" NPSM and hose clamps, but good luck with that.

The Alphacool systems/components are getting good reviews here at the moment, although I haven't tried one. Could be that the suppliers are just trying to get us to buy them though. 🙂
 
So do you have any with cpu scores?

Sorry IcBIUsCrn, but I missed your last post. I can run CPU benchmarks on the wife's PC if that's all you want to see. Haven't done 3dmark on it because she only has an x300 vid card so the scores wouldn't be very relevant. I can run some on Sisoft Sandra '07 if you want. Best I can get is 4.2GHz with her air cooling though.

Also did a write up with screen shots for CPU-Z and memory bandwidth on extreme overclockers forum if anyone is interested. 🙂

well you posted this "I'm currently posting this @ 4.3GHz (1.65v) and stable. Ran 3dmark05 for a couple hours with no problems. Here's a benchmark for any doubting Thomas's. 🙂http://service.futuremark.com/compare?3dm05=2036789 "
But there are no cpu scores on the 3dmark cpu bench mark
 
Right, which I tried to explain is because the CPU tests results on mine are half of her scores at any speed, (and not from throttling down) and the CPU is not showing on CPU-Z. I thought it was due to chipset support for the 975 until I realized TG's review tested on the same MB and didn't have this problem. So if all you want is from the 4.3GHz, it'll have to wait until I get the problem sorted out. I expect to pick up another CPU on Monday, but if that's not the problem it'll be longer to get the MB replaced. 🙂
 
I finally got enough components to set up a temporary test bed for my 805. Setup:

805D
STOCK Intel Cooler
Gigabyte GA-8N-SLI
2Gb Patriot 667 DDR2 (5-5-5-15)
7900 GT
80Gb Maxtor
Toshiba DVD rom
300Watt Generic PSU

Notes:
No lapping. Stock cooler with thermal pad mounted straight on.
No case. Loose 60mm fan blowing air over northbridge heatsink. (Was hot to the touch before I plugged in the fan; now it's cool.)
Components sitting bare on my desk!
WinPX Pro SP2 installed with latest drivers.
Haven't even flashed the bios yet--Rev F3 (most current is F5 I think)

I'm up to 3.5GHz with only FSB tweaks.
VCore shows 1.29v.
CPU Temp at idle = 23c/75f.

Benchies so far:
3D05 = 8409
SuperPi @ 1M = 38

I've run 3D05 about 5 times in a row, with no artifacting or crashing. I have to say, this is absolutely awesome for a $130 chip, and I can't wait to build a proper system with it. I have the luxury of running it side-by-side with the rig in my signature, so I've been able to run benchies on both for comparison. Right now the new machine is blowing away my old one. Woot!

I plan on throwing a Gigabyte cooler on and putting it in a proper case with a better hard drive, but this will do for now. Can I just tell you how stoked I am that I'm running an awesome gaming rig from 2005 next to an awesome rig from 2006? I feel like I should do some folding or something...

Anyhow, I'm not going any further until it's housed and cooled better. But hey, 3.5GHz is what, better than a Pentium EE 840 which costs around $950? Yeah. This rocks. I've spent $750 and I got a chip, mobo, ram, and a nice video card. Wow, just wow, is all I can say.
 
I have purchase the exact CPU and Mobo with a water cooling Kit.

I am stuck to which memory i should purchase.

Can someone please advise to which memory would be ideal for this project ?

Regards
Anthony.
 
i was not saying that the older bios supports fsb adjustments just that was the latest bios when i had the motherboard i am sure there has been newer bios updates that might let you overclock but i doubt it.

testbenchdude: well its kind of "unfair" to proclaim such a sucess when its not mounted in a closed case. Just trying to say once in a case you most likely wont get such an overclock.

also just cause you get 3.5ghz does not mean you are "beating" a 840ee
 
I could only get the chip to remain stable at 3.1. The chip sits on a water cooled Msi P4n Diamond with a 500 watt power supply. I upped the voltage a bit, but no joy. Memory timing were set to 5-4-4-9 at a speed of 800. The highest FSB I could maintain was around 630.

A 4.1 GHz Dual Core at $130 - Can it be True? = No, atleast not for me. The chip at 3.1 seems really happy and runs very cool. When I jumped it from 605 FSB to 630 the water temp shot up 10 degrees cel. I was hoping to get a modest 3.4 ghz out of it.

If anyone has any ideas let me know. I am wondering if it could be the mobo that causing the lock ups?

Still at 3.1 this chip is a good value I replaced a single core 571 with it.
 
I'm at 3.6ghz right now without upping the voltage. I ran a 12 hour render for computer animation and my CPU was at 60C.

When i bring it up to 3.8ghz it crashes when it loads Windows.

I have a CPU Vcore voltage setting in my BIOS. I have it on auto but can pick from many different voltages. Only problem is I don't know what I should bring it up to. If I raise it too high I don't want to burn the chip out.

So what's a respectable voltage for trying to hit 3.8ghz-4ghz?

I have the wife's puter running 3.8GHz with the CPU voltage @ 1.45v. I needed 1.525 to be stable at 4.0GHz. This is pretty low and safe. I worry about anything higher than 1.5375, although I've had 2 of these CPUs @ 1.6v with no ill effects. 🙂

Anthony, save your $. I've done a comparison to DDR2-533 and DDR2-800 (see link below). There is no payback to spending more on DDR2-800 for this CPU. It'll still run fine, but there is no benefit from running the DDR2-800. If you plan on using the RAM later for something else, then by all means go with the DDR2-800. Otherwise Corsair Value Select DDR2-533 will perform just as well on this setup.

What some are missing here is that the SmithField core runs at 133MHz (2.66GHz) with a locked multiplier of x20. This means that even at 4.0GHz its only putting out 200Mhz X 2 = 400MHz for RAM. Still well below 533, let alone 800. The link shows that memory bandwidth is identical for DDR2-533 and DDR2-800. Every memory benchmark that I've run to date shows the same results. 🙂

There is different latencie values ..

C3 is nearly twice the price of C5.

Is there much difference in preformance ?
 
Ever heard of newegg.com? Also, the lower the latency the better.
Google it and learn about it before you spend $$ on it.
 
I was inspired by Toms article and decided I didn't want to play the waiting game where you put off building a decent system because of the dreaded "better/newer architecture coming out soon" excuse.
I have a 3500+/6600gt system I built in Oct 94 and I can still play all the games I own including Oblivion. However I do a lot of video work from building dvd's from scratch to re-encoding, and have been wanting a dual core system.
One thing I have noticed, is that I haven't heard anyone talk about how loud or quiet their system is compared to the speeds they are running at. I know anyone can build a really fast system that sounds like a jet engine, but that's not very enjoyable.
I also haven't seenmany posts on how much they are spending building a computer based on the 805 overclock.
I have my last shipment of parts coming this week, and will post build results from sound tests to overclock and performance numbers.

BTW, my build cost for my new system was under $1100 :) . I was also pretty happy to discover that my current system is still worth between 1200 and 1500 retail, so I should be able to recoup near or all of my build cost if I can sell it locally.
Only time will tell if this new build will keep me satisfied for another 2 years :wink:
 
The wife has a Gigabyte G-Power Pro on her CPU. Overclocks to 3.8 with the fan all the way down (silent). Have to turn it about half way up to get 4.0. The fan is noticeable there, but still not bad at all. To get 4.1 the fan has to be all the way up, and gets pretty noisy.

I can't really compare prices with you guys in the US. We use top of the line MBs and PSUs (learned a long time ago that its not worth it to skimp on those, as both can take everything with them when they go). The rest (case, dvd burner, RAM) is some of the cheapest stuff on the market.

Another thing to keep in mind (that I haven't tried yet) is that good DDR2-533 may be able to go below stock timings with this setup. The Corsair value select won't, but my Crucial DDR2-800 tightens up to 4-3-3-8 (4-4-4-12 stock) @ 4.3GHz/860MHz (1:2).

Hard to believe a used system with a 3500+ is worth that much there. New ones are selling for half of what they did a year ago. I have a slightly used 3500+ Winchester here that I can't give away. Same with a slightly used 3700+ San Diego. Offering 2 year warrantys on both. Good luck with that. 🙂
 
not to be a prick but $1200-1500 for a 3500+6600 gt system, you must have a raid setup with a few raptors.

2nd your old sytem was not bad (pretty decent actually) all that was needed was a new video card and maybe some overclocking so you could have held out for "better/newer architecture coming out soon" . If not at least till the price's drop on the current one's.
well i have 1 805 that is at 3.8 on air and it is my own little "747" mostly i blame that on the case/psu fans that i am in process of upgrading. (case is a thermaltake xaserv) I am also getting external watercooling so that might add some to the noise.
My second 805 is not loud at all its at 3.5ghz w/stock hsf.
as far as money $1200 for the one in my sig and less then $500 for my budget system that i bought everything used besides cpu/mobo combo.

The one thing i'd like to point out is that currently while not only sounding like a small jet engine its as hot as one to. Left it running some stability test in a closed room and after 12 or so hours i had my own sauna. It was a significant temp increase. I never plan on using it for that long but even after 4 hours it still cooks.
All i wanted it a go between from a sckt 478 to conroe thats why i picked one up so another 6-8months is all i need.
