CPU problem, p-31-ds3l

[GanjaStar]

hey guys, I dunno where else to ask, and since the gigabyte experts who helped me overclock a few PC's are here, ill give it a shot.

if its ok ill post the link to the thread where everything is written, let me know If its not, ill just repost all the info here.

Hopefully somoene has more experience with an issue like this :) thx in advance

No need to copy the linked-to thread here.
We need details about your system.

Follow steps #1 - #4 in http://forums.tweaktown.com/gigabyte...tml#post295784, post #5.
Copy the P35 bios template into NotePad or any plain text editor, fill in your current bios settings and post your bios settings.
Ignore the remainder of the post.

EasyTune6 does not work with P31/P35 systems.

Any questions?

Another thing to consider. I've had this CPU in my own rig before passing it down to my brother. It was working fine with pretty much the same BIOS settings on a p35-ds3l mobo. CPU was performing as it should, unlike now in the p31 mobo where performance is halved be it stock 2.4 or 3.0ghz


And I apologize for forgetting the proper procedure for help threads ;) Thx for the help

Re: CPU problem, p-31-ds3l

Your CPU default voltage is 1.35v why are you setting it below for overclock? Try 1.35 or more.
What kind of CPU cooler do you use?

[GanjaStar]

Re: CPU problem, p-31-ds3l

I tried voltage up to 1.4 in small increments, same bench results, same issues as described, just more heat. the voltage im using is the lowest voltage that's stable with a 3ghz overclock. By stable i mean intel burn test or anything else you throw at it. It's a crash free system. cooler is the stock heatsink with the fan replaced. I installed a panaflo 80mm fan on top of the stock heatsink. Temps are fine, idle 30 C max load whn testing stability 60 C

Re: CPU problem, p-31-ds3l

Does that application recognizes that you have 4 cores?

[GanjaStar]

Re: CPU problem, p-31-ds3l

its a dual core, and yes, all apps recognize the two cores. Its a strange issue that i've never encountered. a corecctly recognized CPU performing sub par.

Re: CPU problem, p-31-ds3l

IInteresting, are you using an add-on graphics card or the built-in graphics?

[GanjaStar]

Re: CPU problem, p-31-ds3l

8800gtx, theres no built in gpu on this mobo.

Re: CPU problem, p-31-ds3l

Oops I was confusing with another thread.
Can you post a screen capture of the Neuclerus results (Alt | print screen to capture the front active window only)

Re: CPU problem, p-31-ds3l

Seems that memory performance are tthe issue here.
Try to lower Static tRead Value as much as possible.

[GanjaStar]

Re: CPU problem, p-31-ds3l

changed mem from slots 2 and 4 to 1and 3. put tread static at 6 and 7, anything lower wouldnt post, and the bench scores and memory read/write values were pretty much the same.

thx for trying though.

It looks like something is wrong with the mem controler on the mobo? Not an expert in this area myself.

Re: CPU problem, p-31-ds3l

Don't know really as the cache speed is low too, I get about dounle at 3GHz.

Re: CPU problem, p-31-ds3l

Can you test with a different set of memory?
Are you using memory slots #1 and #3?
It looks like you are running with "mismatched" memory, from your report:

DIMM # 1
SMBus address 0x51
Memory type DDR2
Module format Regular UDIMM
Manufacturer (ID) Kingmax Semiconductor (7F7F7F2500000000)
Size 1024 MBytes
Max bandwidth PC2-6400 (400 MHz)
Part number KLDD48F-B8MN5
Number of banks 1
Data width 64 bits
Correction None
Nominal Voltage 1.80 Volts
EPP no
XMP no

DIMM # 2
SMBus address 0x53
Memory type DDR2
Module format Regular UDIMM
Manufacturer (ID) Nanya Technology (7F7F7F0B00000000)
Size 1024 MBytes
Max bandwidth PC2-6400 (400 MHz)
Part number M2Y1G64TU88G7B-AC
Serial number 09A60853
Manufacturing date Week 32/Year 10
Number of banks 1
Data width 64 bits
Correction None
Nominal Voltage 1.80 Volts
EPP no
XMP no

2GB of memory with vista or win7 is probably hurting your performance.
My results are using 8GB of 1066 rated memory running at 874MHz with 4-4-4-10 timings.
My cpu speed is 3.496GHz using 437 x 8.0 settings with win7 SP1.
