E6700 OC. What do I do now? Test results inside

post #1 of 12
Thread Starter 
So I was wondering how my cpu would perform when underclocking the ram so I did a bunch of tests. I used pcmark05 to score performance. I also ran 3dmark a few times, but didn't see any signifigant gains or losses while messing with the cpu speed.

I tested a bit with memory ratios and the multiplier. Here are the results.


vcore set at 1.4 and mem set at 2.1V

Multiplier .......FSB:RAM ....... CPU(Ghz) ....... PCMARK05
10 .............. 2:3 ....... .......2.66 ....... ....... 6938 (stock)
10 .............. 1:1 ....... .......3.33 ............... 7734
10 ....... .......4:5 ....... ....... 3.33 ....... ....... 7955
9 ........ ....... 4:5 ....... ....... 3.15 ....... ........7644
8 ........ .......1.1 ....... ....... 3.2 ....... ........ 7731
10 .............. 4:5 ....... ....... 3.5 .............. 8229

Temps were all high 30's idle and high 50's load. Except 3.5. it was low 40's idle and high 60's loaded.

I tried to get to 3.66ghz to get a 1ghz OC for fun, but I couldn't get it to boot. I cranked up the mem voltage to 2.25 and set the timing to 5-5-5-15. Not sure all the steps to go through once I hit a block. Should I try cranking up the vcore a bit?

do the 3.2 better to have 1-1

Yes, up the vcore a bit if you havent already

I did a 1:1 at 3.33ghz and it was pretty much the same as the 3.2. I did the 3.2 w/ 8 muliplier because I felt kinda retarded having DDR2 800 and running it at 333mhz. According to my pcmark scores 4:5 ratio performed better. Why is a 1:1 better?

I just tried upping the vcore to 1.45 and it still wouldn't boot. Ya think it might need to be higher than that?

I OC'ed to 3.7 once, needed 1.57 Vcore I believe. Temps were pretty high though so I didn't run it very long.

I am running 3.4 Ghz 24/7 at this time 6 hours stable in Orthos.
Temps are 42 idle, and 54-56 load.
I believe Vcore is at 1.475

Cool. yeah I ahven't really done any stability testing yet. Hmmm I got 3.5ghz with 1.4 vcore. Although with no stability testing it's kind of worthless. is you vcore so high at 3.4 for stability reasons?

Can you return the E6700 for a refund? If so, I suggest returning the E6700 and buying the cheaper E6600. The only difference is a cpu multiplier, so you'll end up with roughly the same cpu speed after an OC. It'll save you about $200 that you can use for future upgrades

heh well I got the E6700 for free and that was my only option It's an ES.

Yea, I had to raise the Vcore that high to get it stable at 3.4 GHz.
