Spec me post purchase

Realtemp is perfect thanks Invertigo :)

It shows core1 is 38 at idle which I suspect is good

Reckon I can eek out a little more from the cpu so time to read up on cpu OC'ing lol

Many years ago I OC'd my pc and it corrupted all the hdd's and I have been wary ever since so I have a lot to catch up on (wish there was a site that says 'here, for your ram, cpu and mobo, use these safe and optimal settings')
 
i think it depends on the chip you get :D so not all settings that worked for some1 would work for some1 else the same way,,(if you know what i mean)
 
Just for reference I have the same Motherboard/CPU, My i5 760 is at 4ghz and idle's between 30-35c depending on room temp. and max load in prime95 is 65-69c But i went for the Corsair H50 cooler :D

As Invertigo has said, ideally you dont want it to be much over 70 under full stress.
 
Mayfair I don't suppose you have your bios settings to hand and did you add them in using the 'manual' option?

lol I'm really scared to change voltages etc, bit of a mine field in there
 
The motherboard you have specified does not support sata 3.0, meaning the purchase of the c300 is quite pointless as on SATAII the speed will be capped at 285mb (read).

Either change the mobo, or change the SSD. The vertex 2E is a better option, with a lower price,a 285MB read spec that works on SATA II and a much, MUCH higher write speed.

The p7p55d-E model does support Sata3, its the non '-E' ones that are just sata2.

I should know, I have the same board :p
 
Mayfair you rock, I'll have a play later today after I have setup my backups and images, just in case :)

As said above, it does support SATA3 via IO level up button which sacrifices the x16 lanes to 8x lanes on the main PCIe gcard slot.
 
OK might need to start a thread in the OC subforum but I had a play and things seem to be ok *fingers crossed*

Can anyone have a quick look at my settings and tell me if they are ok please?

CPU = 4GHz
DRAM = 1600MHz

the above are nice round figures achieved by the below

CPU ratio = 20
BCLK = 200
PCIe = 100
CPU voltage = 1,344
IMC voltage = 1,375
DRAM voltage = 1,600
CPU PLL voltage = 1,790
PCH voltage = 1,050

Idle is 43 celsius

If this is ok do I now need to run prime 95 and memtest (version?) and where would I get these?

EDIT: Just ran 3dmark vantage 1.02 and got a score of 8750 and max cpu temp went to 68 - is this acceptable?

MODERATOR if you think it's appropriate please move this thread to the OC subforum :)

Agreed. Prime is purely a burn in app for most people. Your CPU will never come close to that temp doing normal work or gaming etc. 99 degrees is the TJmax of Nehalem chips so you still have room to breathe
 
I played around lowering the cpu voltages as I wasn't comfortable with the temps within prime

lowered cpu voltage to 1,250 but prime bsod, upped it to 1.275 and the prime application crashed shortly after starting. Does this mean I should up it a bit more or is the application faulty?

Before prime crashed it ran for 3 minutes and max temp was 71 so least it's going down
 
No - prime crashing is definately your OC unstable - too little volts. Dont worry about 80 degrees when stress testing - although if that's in Prime you should try IBT on max memory setting - I find it around 5 degrees hotter than Prime. 5-20 runs of IBT is also generally considered a quick way to find instability when adjusting settings (minutes) whereas Prime tends to have to run for several hours so is usually used as a final check.

Your CPU PLL looks low (lower even than stock 1.8) so maybe a bump up there will help - I run 1.9. Your IMC (assuming that is what is called qpi/vtt in my gigabyte BIOS) is also pretty high so could be contributing to temps. I can get my 200 bclk stable with only 1.3 on the qpi/vtt but your mileage may vary. It will also be useful to get a handle on your vdroop - i.e. how much the vcore drops under load (compared to what is set in BIOS) and see of turning on LLC might be helpful if it's not already. You can use CPUZ to monitor volts under load. You might need your ram volts a little higher - mine for example is rated at 1.65V if running at 1600MHZ (as set by the XMP if using auto settings). Sounds like your nearly there with a decent 4GHz OC anyway. Here's my full settings for your information...

20x200
mem multi x8
qpi ratio x32
pci clock 100
ram 9 9 9 24 (XMP disabled mem setup manual with performance enhance 'turbo')

vcore 1.375 in BIOS (CPUZ shows 1.36 at idle and 1.392 load with LLC on level 2)
qpi vtt 1.3
pch 1.1
cpu pll 1.9
ram 1.66

cpu and pci clock drive both 900mv

As you can see my chip isn't the best one to come out of the factory and I need pretty high volts for my 4GHz, but it's all within spec so not concerned. Kept under control by my H50, but if you need core volts like me your cooler may struggle.

Many thanks for your info Liampope however it's a little over my head lol :( :)

I manually set the cpu to 1.3v and ram to 1.6v, everything else is on auto and things seem to be stable now. However if I set the cpu and ram to auto then their volts go to 1.344 and 1.65 respectively, should I just set them to this or leave as is?
