E6700 @ 3.5 ghz
Corsair XMS2 6400 epp @ 875 5-5-5-15
Asus P5B Deluxe Wi Fi App
EVGA 7950GX2
Game Extreme 700 watt

I think my voltage is too high. It seems like in order to break through to 3.4+ I need to feed my cpu alot more voltage then what I have read in various reviews and such.

I am at 1.56 v core in bios, voltage monitors read it @ about 1.52
ram is 2.25 v
Idle temp mid 40's
load temps really gets up up there, over 60 for sure. I have read its best to keep it under 60 on load.

I have reseated the processor with AS5 once, I did notice the clamp over the processor wasnt completely level, at least to my eye. Regardless, with an E6700 and decent air cooling ( Zalman CNPS9500 ) what kind of voltage should I typically need for a 3.5 ghz OC, and what kind of temps should I try to be within.


Off to work on levelling the clamp

Thnx for any tips or info
 
1: Every chip is different. Some people cannot even reach 3.5ghz, so you should be happy about your 3.5ghz overclock. I had an E6700 and it would never go beyond 3.2ghz.

Some chips are good, others are great, so some may only need a bit more voltage, while others will need 1.5 and above. It's a matter of luck.

And 1.52 doesn't seem that bad anyway!

2: The Zalman 9500 LED sucks with C2D's While overclocked. I had one myself and had to change it since I couldn't keep up.
Get yourself a Tuniq tower 120, a thermalright Ultra 120 or a Scythe infinity!
 
How stable are you at 3.4ghz?

If you need something like 1.4v to run 100mhz slower, I'd definitely do it.

As was stated, each chip is different... Most chips dont even hit 3.5ghz... so, if it takes 1.5v, it takes 1.5v.

However, more than 62'c is *not* recommended.

LOL my e6700 hits 60 when it's not even overclocked (62 actually...bleh....I need water cooling). The stock cooler sucks and I lost the screws for my zalman. :(
 
Thnx for the response guys. A bit more info.

I was playing Oblivion for 8 hrs with no crashes @ 3.5 ghz, the ram was OC'd from 800 to 875 5-5-5-15 , ram voltage set in bios to 2.25.

My bios setting for CPU voltage was like 1.58, but all my voltage monitors said it was closer to 1.53 volts, I assume the bios is incorrect.

In regards to stability my gaming, 3dmark06, Super Pi, Prime 95 are all stable.
Orthos Blend is not stable, I do get errors within 1 minute.

I have been using memtest to isolate memory or cpu as the culprit. I want to stay at 3.5, but the temps are too high, I am over 60 C, would like to be at or under 60 C. I am going to take your advice and look for a better CPU cooler.

I am trying to squash these Orthos Blend errors at, but I just sent away my 7950GX2 to stepup with EVGA to an 8800GTX. Going to have to find a replacer gcard to tinker with the OC ( serching closet and old newegg boxes ).

My settings are with latest p5b deluxe bios @ 3.5 ghz

multiplier 10
cpu freq 350
dram freq 875 5-5-5-15
mem v 2.25
cpu vcore 1.5875 ( reads 1.53 in all software voltage monitors )
fsb term 1.45 v
nb core v 1.55
sb v core 1.7
ICH 1.215


My other OC as a reference that is completely stable ( I stepped up the voltage one tick by 100 mhz from stock )

3.2 Ghz
1.4250v ( voltage monitors state 1.39 v )
ram 800 4-4-4-12
ram voltage 2.25

I dont have the other settings because my gcard is gone

Edit my highest overclock I was getting close to 70 C cpu temp, way too high. Something isnt right about my cooling.
I am happy with the 3.5 Ghz OC because its about the limit of the OC on my ram with a 5/4 divider. Or maybe I could feed the ram more voltage? hmmm

Anyone know the " safe " parameters for ram voltage for XMS2 Corasir 6400 epp ram, package says runs 800 @ 4-4-4-12 at 2.1 volt but its seems to work at 2.2 v. I have heard 2.4 volt is safe but I dunno for sure.

Thnx and sorry for the ramble
 
youve got the best intel mobo for overclocking on the market right now. Given proper cooling, i think you suould be fine as far as the level of OCing youve done. you may need to adjust some settings thats all.
 
Yes this is where my knowledge falls short. What I need is an education on the multiplier and how the resulting fsb effects the stability of the computer. I am going to drop down to 8 multiplier and see how things go.

This might sound like an idiotic question, this is my first chip where I can adjust the multiplier, but how does the resulting fsb speed, if set higher with the multiplier, change the dynamic of the overclock to a more stable level if all the parts are running at the same speed, the only difference being the fsb is higher.

I found a Tuniq Tower 120 and its on its way. Upon research I found alot of information stating the Zalman I have has issues. Thx again for the tip.

Any education on fsb and multiplier will would make this novice overclocker happy : )


edit: one additional question. I am convinced my HSF is not making good contact with my cpu. The motherboard load clip seems to be slightly uneven. Is it possible to fix this problem or remove it entirely so that the HSF makes 100% flush contact with the cpu, and if so is this safe for the cpu, assuming the HSF is installed properly. Just worried about pressure on the cpu itself. Thnx again.
