This Looking Ok?

Ok well I havent O/C'd in a long time and whilst I wait for all my new fans / heatsink to arrive I couldnt help but have a mess around with my new stuff on stock cooling...

Motherboard: P5K-E
CPU: Q6600 - Low Energy
Ram: 4G Geil PC6400 800Mhz Ultra Low latency blar blar etc..

So I have read various threads here on the boards and at the moment I have my ram set to snail pace whilst I see what I can get the CPU to do..

Currently I am stable (well 2 hours into a Prime95 Test) @ 3.204 Ghz (356FSB) running a Vcore of 1.300.. I am getting between 54c -56c On Full Load depending on the core (seem to have 2 hot and 2 cold ones?! this normal?)

Does that look normal?

Also running a vcore of 1.300 it is showing at around 1.27 with a drop to around 1.24 on full load is that alright??

Just another thought! All questions today... I had a look at keeping the fan on my graphics card (8800) at full speed all the time yesterday.. nvida controll thing wouldnt let me change the fan speed after some reading seems there could be a BIOS setting I need to enable/disable anyone got an ideas on this for my board??

looks nice mate, if the temp difference between the cores on load is too great (~10c or thereabouts) you might consider lapping it. Seems like you'd get 3.4 out of it easily enough.

Difference on the cores is only 2-3c or so nothing major just wanted to check that was normal...

Ran a 4 hour Prime95 test and no problems so am up to 3.29 Ghz now have had to increase vcore to around 1.33 and temps have gone up quite a lot running around 58/59c loaded now so i think thats probably the limit to my stock cooling although is nice to no I should have a nice margin on top of this when I get some real cooling in the case...

Have noticed I need around 1.24/1.25 vcore on full load for the CPU to be stable will this trend be typical as I increase the overclock? If so will make finding stable vcore values easier!

That's particularly good for a stock cooler. have a look here for some highly-o/c'ed setups, vcores, temps, etc.

ok well back from an evening out and been looking over the log on my prime95 run at 3.3ghz and althought there are no errors on the run after 4 hours I have noticed that in my logs from the asus program it notes on a couple of occassion my vcore droping from 1.25 to 1.16 / 1.17 and then going back up again.. think this is just a reading error? Prime95 hasnt return'd any errors and coretemp is showing stable temperatures still 58/59c after the 4 hour run.. do i need to be concerned?

Also the Mobo got quite hot around 48c normaly runs idle at about 36c think perhaps this messed some readings up? definately need some better cooling in any case before i push this further!

In Prime, you have to go to the Advanced menu, and check Round-Off Checking (iirc), to ensure that it faults on errors.

Sorry if you've done this, but it defaults to unselected.

mobo temps at 48c do sound a little hot, tbh, maybe a stalk fan over n/b?

I have the rounding on

Cooling wise atm I just have two case fans and the cpu stock heatsink... I have a load of stuff on my wishlist just ran out of money buying the rig this month

so will have to wait till mid november now and pay day...

I do plan on getting and lapping and IFX-14 and setting that up with two delta's.. also replacing my case fans with deltas and getting an extra 80mm fan for the side of the case as an extra exaust point.. Am replacing the deafult heatpipes on the motherboard with a north & southbridge cooler and some memory coolers over the mofats. So will see where that gets me and then take it from there..

Am considering perhaps a water setup.. but I have no experience of water and for it to be better than a high-end air setup I am guessing it going to be expensive?
