Post your current Intel CPU and Overclock here

[trt740]

Guys I had a e6600 I could get up to 4.005 ghz and super PI it every day clock was 3.6ghz at 1.475v. I sold it with the intention of getting a q6600 but since most being sold for the next few months are still b3 chips I decided to wait and I bought a e6700 b2 stepping for 235.00 shipped to hold me over. What is the max every day clock I should exspect on air I have a Scythe infinty air cooler with dual 120 fans on it and a EVGA 680i nf68 A1 motherboard. Is 4.0ghz realistic 10x400 for everyday use on this chip. Also how does it compare to a e6850 which only has a 9 multiplier but has G0 stepping. Any ideas.

My OC sucks

[ol'norton]

Is that with stock HSF?

[RoachBurn]

Yeah, I wanna get a Thermaltake 120 Ultra Extreme but stupid NCIX doesn't carry constant stock anymore so they don't list it as avail.

Can't push it anymore, or memtest -freezes- (not fails)

Any suggestions on how to push it further are appreceated

[huncherman]

That's an awesome low-voltage overclock (if vcore on CPU-Z is correct). As for advice, would need a little more info on what you have tried to push it further. You may have hit your FSB limit, either chip or motherboard.

[buzh]

Aww, turns out it wasn't too stable..

Anyway, I've made a new thread here:
http://www.bleedinedge.com/forum/sho...d.php?p=234488

with complete specs and all the gritty details for your amusement!

PS: The voltage in the above screenshot is not correct, cpu-z seems to only report the rated voltage on C2Ds, not the current voltage.

Well, it seems to have all been worked out now

[rscl]

For XBX2 users:
vCore: 1.600V in BIOS, 1.57V actual (idle), 1.55-1.56V (load)
vFSB: 1.375V
vMCH: 1.600V
vDimm: 2.12V

Mem won't OC another MHz above stock, this is the end

[ol'norton]

I'm having a little trouble believing you got the only set of C4's that won't go over DDR-800.

I've never had a Badaxe 2, so maybe someone here who has can help us out. But try this:
Put your VDimm up to 2.225V
Your Memory on 5-5-5-18
Your "Reference Frequency MHz" on 333
Your "Memory Frequency MHz" on 800
And your "Host Bus Frequency MHz" (FSB) on 370
If that boots (& my calculations are correct) your memory should be on DDR-888 (5:6 ratio) Then just creep your FSB up & see how close you get to DDR-960.

[rscl]

thanks for your advice,
I have not tried the 1333 nb strap, but setting ref 333 and 800 mem will decrease performance no longer making it worthwile to reach DDR-960 5-5-5-18 for example.

At least when I tried 1:1 on 400 FSB with both 1066 and 1333 strap, the performance difference were quite large.

I have given up on that issue, going to get new mems in the future... thanks for your interest in my problem though.

[ol'norton]

Sorry I thought you meant your memory couldn't go over 800MHz, as apposed to not being worth it.
Even if you could get to DDR2-1004 on the 266 strap, I think you would take a hit. The 975 boards seem to like 1:1 ratio & cas# 4.

I got under 12 seconds on a 975 board with PC-8500, in spite of the fact the memory could run tighter & faster. I got my best time with 1:1 & 4-4-4-10

And 'Just Learnin' got this incredible aircooled score with PC-6400 ram.
At the time I looked around a lot & couldn't find a better air or watercooled time with 4123MHz. Including well known overclockers with the same board & CPU & using PC-9200.
The chipset becomes a bottleneck & you can't use the extra memory performance.

I'm doing 14.1xx at SuperPI at 3600MHz, I suppose that is ok.

[ol'norton]

That is excellent for settings that are Orthos stable.
See if you can catch Just Learnin's 3600MHz time. 975 board & PC-6400 ram

[rscl]

I have never booted on higher MHz than 3600 MHz, and SuperPI states that best 1M speed calculated 14.141, although I'll never beat just learning... his memorys can run 3-3-3-8 on DDR2-800. cheat

edit: what voltage did he use to get 4100MHz on air? I don't want to say it's all lies but I refuse to believe it's Orthos stable on 4100MHz with reasonable temps (below 70C) on air.

I had 43C on load with stock vcore and 266 MHz and I consider that godlike, 63C @ 1.56V (load, vdroop from 1.57) at 3.6GHz. I can't reach any higher speeds without higher voltages which the XBX2 won't provide me. Maybe his CPU does not need as much voltage tho, I dunno. would be interesting to know at least
