Overclocking Noob Has Requested Help From the Masters

[ZachHays]

I recently acquired an asus p6t ws pro lga 1366 mobo... i then purchased 12gb of gskill ddr3 and a w3570 and put my gpu in it and i have been using it for my main pc for about a week. its an improvement over the fx 8350 that i was using for a while. I just bought an x5650 cpu because i want as many cores and threads as possible and it was a great deal for $15 US... it will be here soon... until then i would like to know how high i can push this thing on an air cooler rated at 150w tdp. I had it up to 4ghz but the performance was dropping every time i ran a benchmark. it went from 650cb to 630 and dropped 20pts every run... i didnt change any voltage settings and i would like to know what im doing wrong... i dont quite remember what my settings were in the bios for my 4ghz oc since it failed and i went back to 3.2ghz


Specs for this pc are:
Xeon W3570 @stock
12gb Gskill DDR3 1333
Strix Gaming RX 460 4gb
CX650M psu
120gb SSD
1TB Hdd

Howdy dear 1366 sir!

How high did your temps get? Inconsistent scores coule be from CPU throtttling due to high temps and when they reach certain threshold, CPU will drop to minimum multiplier to cool off.

As far as how high can you oush it, will depend on your particular cpu and how much voltage it needs at at given frequency.

BTW, 650 score, that's on cinebench r15? I score about 623 when clocked 4ghz using 4c/8t, but temps get up high for continuous operation and will eventually throttle down to 12x multiplier.

Asus p6t del
i7 920
8gb ram 1523mhz

There is certain degree of inconsistency in benchmark. Mine would luctuate +-10 points sometimes. May depend on some tasks running during certain runs.

More detail on the settings would help. You said 4.0 failed? Probably need slightly more voltage. I have an x5650 set at 20x200 for 4.0/ 1.35V and 1600 MHz RAM just to give you an idea

What cooler are you using on that system? Some of the air coolers will handle a heavy overclock fine while others will leave you wanting more but hitting a temp limit.

Zach, we need more info. Particularly about core temps under load. HWMonitor is a good free app for reporting and monitoring voltages and temps. Start with everything at default settings to get a baseline. Have HWMonitor open on the desktop while you run Prime95 for 20 minutes. Attach a pic of HWMonitor immediately after the stress test is run. Use the "Go Advanced" button for that. CPU-z is another free app you should have in your arsenal.

Are your memory modules all the same or are they mixed makes and models?

Specificaly, what CPU cooler are you using? What is the make and wattage of your PSU and your GPU?

Well, the cpu is 130w stock, which should get you about 3.8 or so. To be fair, it should do 3.8 @ stock voltage. Check and see if that works, if not you may have to start bumping vcore a bit. I would probably start at 4ghz with 1.3-1.35v and see what she does. If she passes I would lower the voltage and retest until the lowest can be found, and go up in speed from there. But, you have a 650w psu, that may or may not limit you a bit with the hexacore. I had a 965xe es that needed 1.35v for 4ghz, a 970 that needed the exact same, and my x5690 es needs 1.275v for 4ghz. My 965 pretty much topped out at 4.1 with 1.4v, my 970 was the same, tho it could do 4.2 with 1.55v lol. My x5690 does 4.4 1.4v, 4.8 1.53v. You may get lucky and have a ripper, heres hoping
