I have a similar board and you might need to install drivers for those non SATA drives to be connected. Like on my mobo I have 1 ide connector (blue) and 2 other ones (red). Once the drivers are installed the 2 red connectors will now work, they only support hard drives though, with optical there is a weird glitch and it tries a work around of sorts and makes them look like scsi devices in my device manager, really weird, so all optical drives had to stay on my blue ide connector. Your issue may be along the same line.
 
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.

Ummm....with a water cooled system you should be getting way better than that! My Zalman CNPS9500LED-CU gets me a nice 30c-40c at idle depending on room temps, and it has never gone above 60c at full load running both cores maxed out! So yeah, you should be doing way better than air cooled! Oh, and if you're wondering I don't have much in the way of any kind of air conditioning (so it gets really hot in my place!), and this does effect my temps!

I've been reading the forums and some of you have purchased the GA-8N-SLI motherboard. I've read some reviews on newegg stating that the CPU FSB could not be overclocked, but rather the DDR FSB.

I'm green on the topic. Does this matter? Don't you need to overclock the CPU FSB? Is there a firmware update that addresses this? Does it matter at all? I'm interested in the gigabyte as the price is right, and i've had good success with Gigabyte in the past. It sounds like people have OC'd this board to pretty good speeds.

For those of you that have purchased this board, did the DDR2-800 memory work or did you go down to 667 or 533?

What voltage are you running though mate ?

Am on water and my stats @ 3.8 are:

IDLE: 45c
FULL LOAD: 59c.
vcore @ 1.5v


how long are you running the load test for ???
 
hmmm bizarre ... am using AI booster to monitor my usage and temps.

The CPU Utilization aint working now and it's only showing one CPU ?

Anyone else experiencing this bug ???

Rightmark - no problems
 
Gents what going on with this :

I purchase Corsair 2GB DDR2 XMS2-6400C4 TwinX

When i use CPU-Z its only showing: Single Channel.

http://img446.imageshack.us/my.php?image=screen4ne.jpg

I thought my ram was dual channel. ??

Anyone got any ideas ?

Also what timings do i need to use ??
Click to expand...

Usually when memory is only running single channel its because the 2nd DIMM is in the wrong slot. Make sure they aren't side by side. Usually a slot in between is correct, one on each channel for dual channel.

When my CPU was only showing as one, it was a corrupt Windows installation. Reformat solved it for me.



This is a work in progress. Only the water cooling 4.0 and 4.1GHz links are done, but have a look and let me know what you guys think. 🙂

Well I was running to separate instances of Prim95 on the torture test setting, so both my cores were maxed at 100% utilization...and I just kept running the test until my CPU temp stabilized...and then ran them for a while longer to see if there was any change, but there wasn't. Haven't tried like running for several hours and just walking away yet. At idle my CPU temp varies depending on my room temp. Last night when it was nice and cool in here my CP was around 28c. but right now it's more like 40c...it is a little hot in here right now. But yeah, if I'm getting 40c with just air cooling in an warm room, you should be able to get better than that with water. Oh, and yes I'm also running at my vcore at 1.5v, anything less and you get some stability issues.
 
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?

Here is your answer: Intel Processor Spec Finder if your are getting Box Order Code BX80551PE2666FN or OEM Order Code HH80551PE0672MN you will be getting a 805 with an sSpec Number SL8ZH!

Rezon8, I think I had the same problem with CPU-Z saying single channel but what fixed it for me was a newer version of CPU-Z. I just thought I would suggest that before reformating... 😀

(I get my 805 tomorrow!!!!)
 
I just tried Prime95 for the first time, and I ran the torture test that said would cause maximum heat and power consumption, I only got 51-53C. Well I reccomend those of you to run something like WME9 and encode a video. My CPU utilization only got to 50-60 with the Prime95 test I just mentioned. With WME9 and encoding a video (I reccomend doubling original video resolution and changing decoder complexity to complex) and let that run because I get 95-100% CPU usage and 56-58C. This is all still on my 630 but I am just saying so you truly find your max load temps on those OCed 805's.

The format was to resolve the single CPU, not the memory.

As for erroring on Prime95, any one of a thousand problems causes the same error. Also it does no good to test only 1 core. You need 2 instances of the program running to check both cores.

To see if windows is recognising both cores, start task manager (cntl/alt/del) and go to performance tab. You should see 2 CPUs monitoring usage. If not, only 1 core is working. A format was the only thing to fix this for me (I was ready to RMA the MB, so glad I formatted before I looked like an idiot RMA'ing a good MB).

Another way to verify if both cores are working is to run the CPU tests on Sisoft Sandra, 3dmark, PCmark, etc.. My scores were exactly half what they should have been until the problem was remedied. 🙂

I looked at the system and found the that on of feet on the water block clamp had popped out. Once I got a good mate from the water block to cpu my temps greatly improved.

37c idle @3.6
49c load @3.6

Haven't tried it at 3.8 to if the 64c temp has come down. Really digging the chip, nice for video editing. Been editing all day and system has remained stable.

Not true for every 805. 1.5v is pretty high for 3.8GHz. If you run higher voltages than necessary, you're just creating heat which can shorten the life of your CPU and increase your electric bill for no good reason.

My wife's is perfectly stable @ 3.6GHz with stock voltages (passes all stress tests on Prime95). Runs perfectly stable @ 3.8GHz with vcore at 1.425v on air (passes stress tests on Prime95). That's '6' notches lower than 1.5v, a considerable difference.

Best way to set voltages (IMO) is to start with the lowest that the system will boot to. Run Prime95 for 10 mins or until a CPU fails the test. (Make sure you're testing both CPUs or its a waste of time as its usually the 2nd CPU that fails tests.) Increase voltage 1 notch at a time until the system passes all stress tests.

And keep in mind that just because the system fails with Prime95 stress test doesn't necessarily mean that it'll ever crash from anything else. Its always been my rule of thumb to back off my voltage 2-3 notches from where it passed tests on Prime95 for 10 mins. At that point, they usually fail Prime95 around the 6 minute mark. I have yet to see a system crash using this guide line. 🙂
 
That's very interesting, I perhaps I got a less of an overclocking champ, because I errored out of Prime95 on anything less than 1.5 at 3.8GHz after a few minutes, and at 3.6GHz to run Prime 95 I had to bump it up to a vcore of 1.4 or one of the instances would error out after a while. The funny thing was the other instance of Prime95 running on the first core would just keep chugging along. I do agree with you the best way to chose the vcore is to start with the lowest one that you will boot windows in, and then work up to something that will run Prime95. No point it throwing too much power at the chip and getting nothing for it.
 
I have a different approach to ocing, I pick the highest voltage i want to run my cpu. My case is 1.61 then i increase the FSB . testing with 3dmark06 on the way up, when it crashes i back off the fsb by like 5 then i run two prime95's overnight between 6-8 hours if it has not crashed i consider it stable and even try to back off pcu voltage.
I happen to think if its not stable in prime95 that then the pc is not stable and will eventually crash. and you need at least 1~2 hours to make sure your temp evens out. 10 minutes is just not enough time and wouldnt consider it stable

This is all if you have the right cooling and this is my method and to each his own

The one question i do have for those people running prime95 and getting errors, if you select torure test are you guys setting the memory to use on each core?
 
Hi everyone....never having built my own computer from scratch, never having overclocked and intrigued by the THG article, I visited some online retailers and built the following system:

Pentium D 805 2.66Mhz (of course!)
OCZ DDR2-800 2 GB RAM (dual channeled 2x 1 GB)
Asus P5WD2 (just the plain version, no E, Premium, etc.)
Zalmzn CNPS9500-LED
Sapphire X1900 Radeon w/512MB VRAM
Samsung SATA 3.0GB data / 40GB storage
Lite-On DVD
Arctic Silver 5 Thermal Compound

...I got it to overclock to 3.6Ghz with no problem....quite easy for a noob like myself to figure out....I have but one worry....excessive temps!

My CPU temperatures have been much more like the charts on the THG:

Stock Cooler:
3.32 GHz crash 57 °C
2.66 GHz 78 °C 53 °C

Zalman Cooler:
3.80 GHz 76 °C 47 °C
3.60 GHz 74 °C 46 °C
3.32 GHz 71 °C 46 °C
2.66 GHz 64 °C 44 °C

...going to Intel's website, they say:

Thermal Spec 64.1°C

....what does this mean exactly?

.....going to another website http://users.erols.com/chare/elec.htm#intel

P-D-805 (2.66GHz, dual 1MB L2 - 775) Max. cover temp. 63° C

....how does one measure the "maximum cover temp?"

....and one last bit from http://www.heatsink-guide.com/content.php?content=maxtemp.shtml

Pentium D 820 (2.8GHz) 63°C (similar enough to what we are running here)

Note: Pentium 4 and Pentium D temperature specifications indicate the maximum cover temperature, which is typically lower than the temperature reported by the internal thermal diode. Therefore, your system may be running fine even if the reported "CPU temperature" in the BIOS is higher than the temperature specified here. This does not mean that you're on the safe side, though.
(heh heh....a little bit of CYA here in that last bit! )

I've followed the THG instructions and activated TM2 to allow for throttling back in case temps get way out of whack....I'm running Prime95 right now and I've seen as high as 72C at 3.33Ghz....in line with THG test....

Now for my question....is it safe to run these CPU's into the 70C range?

I find it interesting that the TM2 allows for temps near 80C before throttling back, but yet other sources specify that around 65C is "safe."

Also, what are safe temps for my mobo....its running at about 48-51C. I was unable to find any technical daty at Asus to specify a "safe" motherboard temp.

Thanks....either way, this is a lot of fun, and if I happen to fry my chip, at these prices I could just get a new one!

Jeff
 
Your temps seem really high, can you give us some more specifics about your system? Such as the case you are using, how many fans, how big are the fans, and the room temperature. I'm sure there is something that can be done to get your temps down to reasonable levels.
