That G.Skill is rated at 2.1v. The board is 1.8v stock. So +0.3v DDR2.
Then +0.1v MCH and FSB. Should run steady as a rock.
Once you start getting up towards 4.0 territory. You'll need to add +0.1v or even +0.2v to the MCH. Possibly +0.1v FSB too.
That board is rock solid with the E8400. Have fun. Good luck.

what MHz are you getting from NQs with loose timing? I've been conservative with Vddr, how hot is you ram getting? are you running an extra fan on them (I'm not, just curious)? I saw big gains with 4-4-4-12 but the biggest came from setting 2T on trrd. I saw another forum where gskill rep said 3-6-3-9 subtimings would help but I couldn't figure out how to cross that to this board and he didn't help. I felt like a 15% improvement over stock on $45 ram was sweet, I'd love to get 1080 or 1100 out of them but I figured that would be greedy... (I need to stay with low temps within reason)

I'm running 1070Mhz (2.40) on the sticks. I couldn't get 4-4-4-12 to work at that speed. But the ram HAS to have +0.3v because the G.Skill is rated at 2.1v and the DS3L comes stock at 1.8v. I run my DDR2 at +0.4v without a fan, to be honest. Never had a problem. But you definitely need +0.3v on the DDR2.

I was afraid to bump to 2.1 until I heard from gskill rep. when I looked them up before I saw them rated at 1.8-2.0V. Like you I had to kick them up to 2.1 to get past errors but wanted to avoid heat/warranty issues of any higher. I'd take them to 2.4V and 1100 in a heartbeat if I didn't think I could cook coffee on them.

That's why I was wondering about your heat, even though touch is not a very good test...

I failed big time with the ram.
I also tried 3.8, 3.85, and 4.0 with 1.3 vcore
upped fsb .02 and mch .02 and ram .02

I have the G.S 6400 NQ 5-5-5-15 1.8-2.0

This is what I emailed G.S.:
Hi, quick question
I have 4x1GB sticks of F2-6400CL5D-2GBNQ (1.8-2.0v)
What would be the highest regular voltage I could run safely?
I have a GigaByte P35-DS3L which has high vdrop
400FSB 1X1 ratio 800mhz
normal 1.87v
bios auto 400FSB 2.04v
I love the ram and have it paired with that mobo and an E8400.
Any guidence appreciated.

And their reply:
Hi
This model of memory is good to run up to 2.0~2.1v. maximum 2.15v
Thank you
GSKILL USA REP

Anyway, I tried 3.8 with a 1.3 vcore and that was a fail also.
I must be getting too old.

you've got a way ass-kickin' cpu compared to me. do you have a good cooler? You didn't mention whether 1.3V in cpu-z indicated or in bios setting? I set my bios to 1.35 just to get an actual 1.3 at my cpu, worked ok at 3.2GHz. I would think you would need a few more tenths ov Vcore to get 3.8 or 4. from what I've read that cpu should be fine with it with good cooling. don't trust bios health status, get a free download of core temp or speed fan (easy google find).

If your temps are low keep jacking Vcore 'till it works or you are too afraid. Then you can drop speed to what runs at a level you like.

If you set Vcore to 1.3 in bios it's probably way more like 1.26 at the cpu with this board (that's way undervolt which is fine for temp but I couldn't get prime95 to even run on my E6550 that low, kick Vcore up and everything ran)

Again, what Vcore yopu want to run may depend a lot on your cooler, my 2 cents.

oops, noticed you set ram at 2.0V, my NQs needed 2.1V just to get past errors (+.3V in bios) at any setting and they did not get hot. memory errors could cause your issues.

AC Freezer 7 Pro
running 3.6 @ 1.216v cpuz
1.262 gets me 1.236 in bios and 1.216 actual
1.3 gives me 1.248 actual

1.350 is stock intel voltage, that is not actually any overvolt at all. I'm using the freezer7 also and I get 55C at 100% in a 90F room at 1.3 (actually I set bios to 1.3500 and see 1.312 at idle and 1.291 at 100%) I can't see 3.8 or 4 without bring up your Vcore a little.

that's with 3.22 and 3.15GHz on my weenie cpu (actually I like it a lot, it's just not as nice as QX etc.)

I started with 1.26 then 1.28 in the bios and it seemed to boot fine but prime95 just dropped dead on startup. I went up 2 steps at a time on Vcore 'till it would run. I read about people running it on 1.26 but it didn't work for me. that was at the 3.2 to 3.4 level. I would think you'd have to goose it a little to get 3.8-4.

duh, your .45 cpu takes different V. I would think the same theory applies. I've seen this board do 575fsb, you could try 7X multi at 500 to get you memory squared away then up to 8 or 9x. You would probably need to run 5-5-5-15 or looser.

I would narrow down what the memory will do with known ok cpu settings then bump up the cpu. I like the memtest boot disk (it's a boot option on the ubuntu live disk if you don't have a floppy.

Actually, our tests showed that Wolfdale responds very good to Vcore increase. But we didn’t aim for record-breaking speeds, so we only increased the processor Vcore in the BIOS Setup to 1.5V that resulted into the actual 1.42-1.46V taking into account Vdroop. This voltage increase is relatively harmless for a processor using an efficient air cooler and is acceptable for systems running 24/7. However, even in this case our Core 2 Duo E8500 didn’t disappoint us at all.

We managed to get this processor to run stably at 4.37GHz. No doubt: Wolfdale CPUs will become another overclockers’ favorite, because Conroe processors could hardly hit these speeds at extremely high voltages and with special cooing systems involved. By the way, our processor running at 4.37GHz retained quite acceptable thermal mode of only 70°C under workload.

from the overclock page: http://www.xbitlabs.com/articles/cpu..._12.html#sect0

probably a better idea than mine... looks like 4GHz is well in you range if you wish.

My vid is 1.10 stock (cpuz)
Max under specf. is 1.3625

[claytona]

my friggin board is still dropping settings. I'm going to see what I can do by dropping fsb and seeing how high i can run the gskill NQs.

I guess your mileage may vary but it seems like taking e8400 to 1.3 or 1.35 (actual) would help you get there, you may not even need that much.

(assuming memory is sorted out)
