winchester 3000+ @ 2.7 on air

[dborgill]

HEy Billwinkle,

Can you tell me your EXACT detail BIOS settings like HTT, voltage, mem settings etc etc so I can try to duplicate??

THANKS!

 

[billwinkle]

hey dborgill how ya doing
first system specs

CPU: AMD64 (WINCHESTER) 3000+@2.70ghz 9x300fsb (1.54v)
htt: 3
MB: MSI K8N Neo4 platinum sli
HD:2x 200GB WD SATA RAID 0
HD:1X 200GB WD SATA
HD:1X 200GB WD IDE
RAM: 2X512 OCZ High Performance DDR400 revision 3
POWER: ENREMAX 480 NOISETAKER
DVD: NEC3500A
VIDEO: GIGABYTE 6600GT (single for now)
cpu cooling ZALMAN 7000CU.

memory voltage is at 2.65
cpu voltage 1.4 + 8.3% (something for everyone to monitor voltage will fluctuate btwn 1.49 and 1.55 according to corecenter).
memory timings still stock 2.5 3 3 6 with 188 divider. effective rate 270mhz.
strangly enough, when I lowered timing to 3 3 3 6 computer would not post.
bios original 1.0 that came with board.
sata raid is on nvidia ports 1+2
dynamic overclocking off
agressive timing off
cpu spread spectrum off
sata spread spectrum off
pcie spread spectrum off
pcie clock 100
cool n quiet off

the only time I have blue screened is when I try to overclock my video card, then run 3dmark05. then set back to stock rerun and no problems.
Let me know if I left anythng out and I will post info.

what stepping?

My chip will be fine, ...right?

Yes it will. mine is also at 1.6V and it's Prime stable for 2 days now. If you check CPUZ you'll see that even at 1.6V, your processor still runs at about 1.55V which is safe for Winnies.

Alright, good. I just hope they release a bios version that actually lets me put it to 1.55 or so.

 

[billwinkle]

You caught me. I am so stupid. I wrote down everything on the chip, now I cannot find it.
Did they make 04 week 38 chips? For some reason that number is stuck in my head. Its running so well I really do not want to take it apart to find out. Sorry.

Just ran sandra, it thinks I have a clawhammer chip installed. It used to show winchester.

does it happen that overvoltage kill the chip instead of heat?

I'm not sure what forum I was reading it on (one of the extreme overclocking websites), but people were frying the on die memory controller with too much Vcore.

 

[dborgill]

So how MUCH is TOO much VCORE?

I can set mine to 1.50, 1.55 or 1.6 -- Is 1.6 too much?

BTW -- I am running at 2.4 GHz stable right now with the following settings:

HTT = 3
Mem = 133 mhz effective
FSB = 267
2.4 GHz

29 C Idle 41 C Full load

Yes, couple days ago I saw someone "losing" their Winchester with 1.55V. Basically the chip ran stable for a few weeks, then became unstable at that overclock... it slowly fades away until it's not stable at stock anymore.

Overvoltage kills chips more often than high temps, and this is specially true with the Athlon 64.

So you think 1.50 is good "safe" setting?

 

[ChineseDemocracyGNR]

That's the max I would use, so yes.

I tried superPI this morning with above settings. It would not complete, so I lowered fsb to 290 and lower voltage to 1.47. that seemed to work. It ran 32m in 28m10s. So even though I am now running at 2610 stable I am very pleased. I will continue to tweak to see if 2700 is still possible with 100% stability. I will continue to lower voltage to see if it will run stable at this speed with 1.4v, which until now I have not even tried.

Anybody have a the GigabyteUltra 939 K8NS board? I am having a heck of time getting speeds above 2.2 ghz!! with my 3000+

Help!

 

[dborgill]

Ok.. so FINALLY with these settings I have my system STABLE at 2.4 GHz:

HTT = 3
Mem divider = 166 (Using DDR400)
FSB = 267
Mem = 221
CPU Voltage = 1.55v
RAM Voltage = 2.7v (+0.2 in Gigabyte BIOS)
And all Manual DRAM settings

The biggest factors I found was giving the CPU and RAM more voltage. Do these seem like safe settings?

Also, no matter what settings I use, as soon as I hit 2.5 GHz, the machine reboots. Could be a RAM thing? PSU? (430 Watt Thermaltake) I have no idea. 2.4 Aint shabby though!

Any thoughts?

 

[billwinkle]

deborgill,
did you lower youre memory timings? For me I was lucky and did not have to lower them. If you did not, then try to lower timing I.E. from 2.5 3 3 6 to 3 4 4 7. See if that will help. Usually when you overclock you have to loosen up youre memory timings to achieve a stable oc. I was odd that my system would only post when I kept my orignal stock timings.
good luck my friend, you are getting there.
p.s. try superpi at 32mill and see what happens

Usually +10% over stock Vcore is considered the "safe zone" for air cooling. That's been the general consensus for years. So approximately +0.15v would be considered safe (1.65v for a Newcastle, and 1.55v for a Winchester).

However, there is no long term data compiled on the A64, and the on die memory controller changes things a bit. Personally I still think +10% is safe, but it will be interesting to see how things pan out in the long run.

 

[billwinkle]

Just an update on how system is going.
I just added 2nd 6600gt in sli mode without clocking down system. Everything is still rock solid. I did lower fsb to 296fsb to remain stable. I have run superpi 32m in 27m10s.
3dmark05 6244.
