I hope cpu burn in on both cores increases my oc..
I had to back mine down from 2500 to 2480 because of some wierd reason, the whole pc freezes at 2.5 now, Im gonna cpu burn in both cores for 8 hrs and then try to get back to 2.5
Any recomendations for burn in to increase my oc, im using stock 1.35V for now until enough bawlz to do Vmod to my mobo..
When i burned in my 3800X2 i run CPU Burnin on both
cores at stock speeds with just under the stock voltages.
I kept running Prime95 untill it was passing for around 5mins then
lowered it untill i found the lowest volts that it would run 5min prime for.
Then simply run dual Burnin for 12Hrs.
I think it has made a differnce as i can hit 2.7Ghz with 1.5v Prime Dual
12hr+ stable.

On a cooler day 2800 should be no problem I hope :)
My X2 is at 70 degrees full load and it's running Folding 24/7. Will it last for the next 2-3 years or will it kick the bucket soon? :stick:
update x2 4400+ on wc 1.75vcore 1.4chipset

i cant wait to see te oc on my mach2 full modded :D
AMD rates their CPUs safe up until 60 or 65 C depending on model.Quote:

However, the above limit is at stock clock and stock voltage. The effects of overclocking or overvolting and at the same time operating at the thermal limit are unknown.
2855MHz :toast:
on water ...

i'm trying to do this now. my 3800+ X2 does 2.75 (275x10) sweet @ 1.525@auto and hits 38C under load on air cooling, but i have to go to 1.65v for 2.8GHz and the first core fails after a few mins of superPI.Quote:

I think my memory controller is giving up the ghost, the strain of running 2gb at 255x11 seems too much for it now :(
Memtest and small FFTs in prime are fine, but large FFTs error immediately
I got my new memory to day 2*1gb ballistix pc 4000 .
Got it stabil on 250*11 ,her is picture after +- 12 hours testing,
My goal is 2800mhz on my typhoon /120mm enermax fan and 2.9-3.0ghz on water :)
2750mhz on air
i just got a x2 4200 and was wondering what volts are safe for benching? & for 24/7?
they only run 1.3V default but some people are putting upto 1.75V through them, i wouldnt even go over 1.65V with my 146 :eek:
they dont half run cold though, my naked 146 is 38C load were has this naked is 25C idle & 30C load :toast:
edit: just run maxtcase & it says 55C :(
is it a good stepping ADBHE 0514UPAW
That's an old one, i've not seen many that old. Never seen ADBHE either. I reckon it might be quite decent, but only one way to find out...
well usually the older ones clock slightly more which is why i went for it so fingers crossed :D
so far it does 2.4ghz 1.3V & 2.5ghz 1.4V :toast:

is this good for a 4200?

ive hit a weird problem with mine, 11x256 (2.81ghz) passes on core 1 @ 1.55V but core 2 fails within 2 minutes even @ 1.62V, changed it to 11x255 (2.8ghz) and its now been priming on both cores for 1 hour with no problems
surely 10mhz cant have that kind of affect and the cpu is still only 36C under load, suppose im gonna stick the ram on a divider with very slack timings & low ldt multi and hope it works (i hate problems lol) :(
EDIT: now running 11x257 (2.83ghz) dropped the ldt to 3x, ram on a 180 divider and slackened the timings slightly and its now going strong :D
seems core 2 is a little sensitive to ram tho :(
Memory controller is the key here. If you relax memory timmings/speed you can get higher but that is irrelevant since relaxing memory you get lower performance. Benchmarks are essential, if you do not get better benchmarks by going higher, it is not worth.
I am now running 3800 at 2.7 GHz but with OCZ Gold BH-5 at 245 2-2-2-6-1, and I have better benches than when I was running it at 2.78 GHz with the G.Skill TCCD crap. I dumped G.Skill (watch me if I ever buy G.Skill again).
im gonna leave it at 2.7ghz for 24/7 as it only needs 1.5V & load temp is only 34C & benches higher than my 146 @ 3ghz :woot:
2.8ghz needs 1.62V & relaxed ram to get it stable so isnt worth it, will do a suicide bench run with it in a day or 2 though as i can get in windows @ 2.9ghz with 1.65V but only bench stable (3dmark)
but this X2 is by far the best £120 ive ever spent :toast:
*offtopic* joe, what was wrong with your g.skill tccd?
i was thinking of getting some tccd, either geil one or some g.skill :shrug:
@ tatts, you got your 4200 for £120 :eek: where from? :stick: :p:
i paid £350 for my 4400 in July :rolleyes:
someone removed the ihs to replace the paste then put it back on and it was 65C idle then couldnt use it without the ihs as they was on air so i got a bargain lol
as for tccd vs bh5, ill take geil or ocz tccd all day long, bh5 needs ridicolous volts which makes it run alot hotter & will kill your cpu if its on low volts. you may get tighter timings on bh5 but A64's dont like it too tight and it ends up being slower

Geil One is the cheapest of this "high voltage" Winbonds so the best to buy. It is also available. Now I use brand new OCZ Gold (BH-5), but I have a lucky pair that overclocks over 250 under 3.3V. I know that is not the case with every pair and since they are rated only 3200 one cannot complain. So I would go with Geil One but the W version.
I have to say that in the past Geil had rather bad customer service that I remember.
I agree on all points (no experience with their customer support, though).Quote:

My benchmarks indicate that 250 MHz 2-2-2-5 is faster than 312 MHz 3-4-4-8, so I agree that good BH-5 is certainly faster than good TCCD. Not that either matters much for real-world performance.
I did find that BH-5 are a hassle to run, however, and reduced to 1 kit for benchmarking and use "nicer" RAM for work.
Ok, here is my OC:
X2 3800+ (Manchester) @ 2.5Ghz, 1.5Vcore on STOCK COOLING!!!
Is this ok? or are the temps to high?
i won't go higher cause of cooling.
some comments on this?
thanks
