so cas2 memory won't be accepted by the A64? piss! when i got my AXP i scoured to get CAS2 mem, now i have to revert to 2.5?
also, is it even possible to get higher multipliers? (like the pencil trick, wire trick, speedstrip, etc...)

i have a A643000 cg stepping, Abit KV8 pro and 512 Geil pc3200 CAS2 memory. will they play nice when i OC? i also have some CAS2 pc3200 from ocsystem.com. i doubt that would be a good stick to use...

your cg core should be fine with most ram. my 3200+ is a cg too, and i can run my ram at 2-2-2-10-1t with no stabilty problems at all.

and about the timings, silverback has got it down.. these cpu's aren't like p4's that are bandwidth starved and don't care as much about the timings..
 
ahhh, so ill be ok w/ ram, but what about the unlocking thingamajig? is it only possible w/ 939 cores or is it even possible at all(even with 754). or is the entire community of people without FX's left in the cold.

BTW Eclipse. reading your location, i am curious. do you like the band Nightwish?

As far as I know that's correct. No one has found a way to unlock the multi's going up.
 
3400 clawhammer (cg core) @ 2.4ghz. using 10x240. 1:1 2.5-2-2-10 on memory (3700EB)
Not quite happy with the CPU brick wall... I presume this probably runs equal to newcastles running 2.55-2.6ghz... (which is not uncommon on water).
Anyone got similar clawhammer cg running better than 2.4ghz?
(must be prime 95 stable/3dmark stable/etc, etc). I am wondering what norm of 3400 clawhammer OC'ing is now (I am on water btw).
 
2.3 ghz, 1.65(could probably get by on 1.55 or 1.6, but im looking for stability)

msi k8n neo plat

mushkin pc3200 at 5:6(190mhz).

true power 430

zalman cnps 7000alcu w/ as5

idle: 43 load:54, ambiant: 38
idle: 34 load: 52 ambiant: 33

im going to try for 2.4 in a few weeks, and then if thats stable try and fin the max, but im fine at 2.3 for now


*EDIT* my chip stepping is:

Doesnt the 3400 run at 2.4Ghz anyway ?

If so you would be better of rung 12 X 200 at CAS 2 mate.

i've got a 3200 clawhammer with a cg core, i can get it up to 2.5ghz stable with about 1.7v or so.. haven't tested for long term stability, but it seems to do just fine with a few cpu intesive programs running.

no, over the hills and far away is actually a led zeppelin song.
 
cf(Eclipse) how did you verify that it was a clawhammer CG revision? I'm looking at one but I don't quite know how to tell, gonna PM you too =p. The one i'm planning to get is stated to have 1MB cache.

Just got in my Chaintech VNF3-250 which is replacing my Asus K8V SE Deluxe. Here's my OC settings:

2400 Mhz
CPU mult: x10
HT: 240
Memory: 200 (1:1)
HT mult: x3
DDR Cas: 3 (1T CMD)

This is just a rough overclock.. laxed everything just to make sure it runs Windows XP and any other programs fine. With these settings, Sisoft CPU benches 11,000+ and memory benches 3,600+. My next step is to increase FSB a little more.. probably to 245 or 250 staying 1:1. Then I'm going to try and fool around with ram timings. What do you guys think? My rig details are in the sig.

yeah, but nightwish is the first that came to mind. and i thought you might like some obscure band from Norway... its ok, i dont really care for them either. LZ is faaarrr better anyways ;)

about how much do you all think i can O/C with a Newcastle CG? 15%, 20% ....400% ;) :D
 
With my Newcastle CG core I have easily gotten 20% OC and I haven't pushed it yet or even had to change the stock voltage. I would expect that 25% is not out of the question on stock cooling. After I get the final OC I will post here.
 
i can barely make it to 2.6ghz, which would be a 30% oc over the stock 2.0

soldur: i can make it to 2.5 with 1.6v, but i need .2v more to get another 100mhz out of it... keep that in mind
 
Has anyone used the auto overclocker in the Asus A8V, and what kind of overclock did you get?
 
Most of my info is in my sig.. 10x240, 1.65v, default vdimm

Anyway, I haven't been able to find a setting to change my multi in my bios. For those of you with the VNF3-250, how were you able to change your multi?
 
is there a bios update for your board? it may have multi's in it. if not, do a google search for clockgen, you should be able to change the multi with that program from within windows

there's a beta bios out there dated 7/29. been using it for 2 weeks now, much nicer than the shipping bios IMHO

Update, 2.45ghz... only thing changed... new mobo :)
Got Asus K8-NE deluxe (nf3-250) updated to latest bios that has LDT and let if fly. Might have little more on it once I get a chance to do some volt modding etc. (original reason to change was lack of firewire, etc but I can't be happier). I think this board is far superior if you want some OC'ing and not afraid to mess with board. (only missing thing is limitation of 2..7v VDIMM in stock form and few voltage adjustment available on other boards..) Memory timing is still 2.5-2-2-10 but for same mhz, I can run memory slightly tighter than I was on VNF3. So far, so good. Just need to find that ultimate CPU.
 
Yo~
I've got an Athlon64 3000+ (CG) running at 2.2Ghz with stock cooling at a Voltage of 1.52. It's put together with a Chaintech VF3-250 and a single 512 stick of Corsair Value Select. Idles at 28 degress celcius and when under full load never goes above 43 degrees. Haven't tried to push it much further, will do that once I get some better quality ram, for now I'm pretty happy with a 200mhz overclock. :D
 
Specs below, I haven't tried too hard really and plan on pushing higher. Voltages are bumped just a bit on RAM and CPU, no Prime95 errors all night. The RAM timings gave me the most trouble (3x512) but I finally got 'em stable and am going to try to shoot for 2.5 maybe...

I got the ASUS A8V with a 3500+.

I'm pulling a solid 2.45 out of the proc from it's stock 2.2 using the motherboard auto overclocker feature at 10%.

I'm using a Zalman ALCu 7000+ cooler without the fan potentieometer thingie connected to it.

I know it's n00bish to do but the A8V pulls it out quite successfully without a problem. I'm still playing around with the BIOS getting familiar with the memory settings and AMD archatecture. This being a Intel Proc owner AMD transplant owner.
 
new speed with low voltage!

240x10 (2.4ghz) @ 1.55v. seems stable after stress testing it for a while.. and the load temp peaks out at 45c with that crazy insane 6800gt pumping out heat too (was putting a load on that too) :cool:
 
Lowered my A64 3000+ CO from 247x10 to 244x10 with 1.6v and no more crashing. Its my crappy hyperx KHX3200AK2/1G limitating the job. Divider set to 5:6 @ 3-3-3-13.
 
235x10 at 1:1 at 1.7 volts water cooled. amd 64 3200+ clawhammer cg core 1gb of geil value ram running at 2.85
 
With good enough case cooling, what would everyone say the highest yet safest voltages would be on an A64 CPU with stock cooling and memory without heatsinks?
 
Recently picked up a Newcastle 3200+ and VNF3-250 to take over duties for my 8 month old CO 3000+ and VNF3-250 which has since been moved to backup/LAN gaming duties. The 3000+ is a pretty decent CO core which runs 2.5ghz stable at 1.76v and will hit 2.6ghz (not stable though even with 1.85v) on watercooling. Now it is air cooled with a Alpha PAL heatsink and 80mm fan at 2.35ghz (235x10) at 1.6v.

The 3200+ is still being fooled with. So far it will post at 2.62ghz with 1.7v, but is not at all stable. 2.55ghz (255x10) @ 1.7v is stable in the brief testing, gaming and Prime95 sessions I put it through. Waiting on my OCZ DDR Booster and then I'll do the vcore mod and see if I can run 2.6ghz stable with some more voltage at 1:1. Both VNF3's I have seem to top out at around 315 HTT. I did fool around with the HTT at 340 once, but have not been able to duplicate the feat.

Temps on the same motherboard and with the same exact watercooling vary massively betweeen the cpu's. The CO 3000+ will idle at 33-34C and load at 45C, but the CG 3200+ will idle at 47-48C and load at 52-53C. Both have had the IHS removed with no real improvement in temps even after several mounting attemps. Maybe a 2C drop. I have also tried 3 different bios's with no luck in correcting the temp difference.

Also have run some tests and verified that using the Nvidia onboard RAID solution does affect my stable overclock. Only to the tune of about 20mhz though, so I've decided to keep running the array since it feels faster to me, regardless of what some recent articles have said about the benefits of Raid. ;)
 
Athlon 64 3200+ 2.2 ghz @ 2.61 ghz.

11x237, memory running at 5/6 so it is not far out of 200 fsb spec, memory is 2-3-2-5-1T.

I am running the Zalman 7000 Cu, pure copper, cpu runs around 37-43c.

Chaintech VNF-250 motherboard.

I am very happy with 2.61 ghz, but I haven't tried for higher yet, hoping for 2.7
 
I've got a KV8Pro 1.1 3400 clawhammer I'm using 1gig Corsair xms4000 I can barely push the FSB at all without using the mem dividers.. I can get 265*9 or 265*8 but cant get past 270 to save my life.. anyone know why the divider should have to be utilized with this RAM?? this ram should provide more than enuf room to push the fsb.. Is this a common problem for all athlon 64's? This board allows only a max voltage of 2.8.. could this be it???/ Thanks

KV8Pro 1.1 3400 Clawhammer
1 gig Corsair XMS 4000
X800 XTPE
Raptor HD
 
Your ram probably has Hynix chips so that 2.8V for the mem is more than enough. You have a ClawHammer, probably a C0 revision that is very picky with memory that makes you run dividers.
 
So, you're still active eh? Maybe you could dig up that link to a 3.6GHz SledgeHammer FX chip on extremeforums you posted a while back? It seems there's demand for it in another thread.

By the way, I'm the guy you had an argument with on page 2 of this very thread :).
 
Thanks for the reply.. You are correct about the CO stepping and it does appear to be the real problem.. I've got 2*512 Ballistix 3200 on the way to hopefully resolve my OC/performance problems.. Thanks again!
 
2.5ghz Stable (9X279)
ram sucks and is on a divider 200:133
1.75cpu/2.8ram
TDX Waterblock
 
just got the thing set up last night

Epox 8kda3j
CG 3000+ @ 240x10, 1.65V
crucial ballistix 3200 @ 240MHz, 2.5, 2, 2, 5, 1T, 2.8V
HT 4x

running prime all day, gonna try pushing it more over this weekend.

stock cooling also, so hopefully this thing has a lot of headroom left.
 
I just joined the A64 Wagon - 2800+ on the Chaintech - so far getting 2280 ghz at stock voltage with the Zalman Cau cooler - temps were pretty decent 34C idle 40 ish load but I just upgraded to the latest bios and now it's 56 idle 65-68 load???

Funny thing is I would figure at those temps the heat sink would be pretty warm but it's not even after hours of Super Pi and/or Prime95...so what temps should I believe??
 
there is no TIM - 7000 basically screws into place so no messing up the mounting - I did the artic silver method for apply compound - I've read the latest bios update screws up the temp readings on the VNF3-250 and I am inclined to agree - I've run Prime95 and CPU stability at the same time - ran Prime and 3dmark - memtest everything I could throw at it - and no crashes dumps or blue screens - :) running right now at 2280 mhz and 412 DDR - I think memory is my limiting factor right now.
