overclocking the amd 64 winchester 3000

[richy]

Hi everyone,
ive just recently upgraded my system to a abit av8 skt 939 mb with a winchester 64 3000 chip and a thermalrite xp1200 cooler, i,m currently using corsair pc3000 ram , i read an interesting article on this forum about how well the 3000 chip over clocks and i was wondering if anyone could point me in the right direction with regards to what sort of oc i should be aiming for and how i go about getting there, thanks peeps..

first disable cool n quiet then drop the htt multi to 4X also disable fast writes, then up the fsb 5mhz at a time ,checking it is stable with memtest and prime95 ,as you only have pc3000 ram?(or is that a typo), run the mem divider asynch to keep the memory clocked low and well within its limits ,if you get to above 250fsb drop the HTT multi to 3X

also dont increase the core voltage untill you have found the limit at default volts ,i get 2.6Ghz with my 3000 before it needs more volts but more volts makes it shed loads warmer

oh and see here

hi bud, i,d just like to say thanks for the information it was very helpful i did some overclocking last night using 3d mark 2001 to test stability(i ran the tests in loops to be sure the system could cope) and i managed to hit 2250 mhz on stock voltage earning a nice 24,000 score in the process.( kept the wife up most of the night lol!!)

I'm currently playing with a Winnie 3000 PIB and an A8V, and so far have been amazed at how far its clocked. I'm using PCI gfx card whilst waiting for 6600GT to arrive, so the HTT frequency hasn't been an issue thus far Its currently running 275x9 (2475MHz) at stock volts :O I've been Prime95'ing it for over an hour so far... Unfortunately, its not my rig - I've built it for a mate

I'm new to Athlon 64 (still running an XP-M in my rig) and from what I've read, I get the impression that running the HTT over 1000MHz is a big no-no. As I can't resist doing some more testing before the 6600GT arrives, I'm going to slap my 9800 Pro in and see what happens when I try 250x9, with 4x HTT and a 5:3 DRAM ratio (due to the limitations of Elixir PC3200).

Have I got an unusually good chip here, or are alot of people getting similar results?

da-ging, thats an awesome link...thank you!!

Whats your temperatures like guys?

Running mine at just under 2Ghz and its only gone up by about 4 degrees!

Whats your temperatures like guys?

mid 50's at full load and low 40's idle @ 2.565Mhz @ default volts

da-ging, thats an awesome link...thank you!!

it is a good link isnt it

[chriswood_7]

Using stock heatsinks?

Whats your temps at stock speeds using a stock sink?

Not going over 42-43C under load here @ 2520. My phone reckons the room temp is about 22C, but I'm not sure thats accurate, as the 'motherboard' temp reads 23C... Does anyone know where the ambient temp sensor is located on A8Vs?

I'm using stock cooling with an Antec SLK1650, so theres a mid-rpm 120mm in the rear and an 80mm duct on the side panel to help.

At stock speeds, temps range between about 27-35C with the cpu fan at 2000rpm

[chriswood_7]

Im using a Gigabyte Cooler 3D Pro, and my temps dont go over 35 degrees when Im overclocking to just below 2Ghz. I think the temp readings are way off but I have one of those handy little guru clocks to monitor the temps real-time, and the temps all seems plausable to me. I havent even tried my chip with the stock cooling so anyone using an ABIT AV8 with a 3000 winny let me know what your stock cooling temps are.. just so I can get an idea of how far to push this thing.

Cheers

I dont know where the ambient system sensor is placed, but if you have good intake you should get pretty close to ambient air temperature inside ur case. I think thats a good sign of a system with good airflow efficiency!

I'll have a poke around later and see if I can find it. Yeah, I'm very surprised at the case, too. Kudos to Antec to making a £45 case with this kind of thermal efficiency. I've got an Artic Cooling unit on my 9800 Pro, which no doubt helps alot - I'd expect temps to rise a few degrees when I stick the 6600GT in...

God knows how accurate the actual temp readings from the motherboard actually are, but I suspect they are on the low side. Then again, it's really doubtful that they are out by more than 10C...

Looks like I've hit the HTT limit on this CPU/mobo combo, before I've even tried to shunt any significant extra voltage through it - its crapping out at anything over 280 HTT and I strongly suspect its the motherboard thats hit its limit. I ran Prime95 for about 15 mins at 275x9 (stock voltage) without errors... Anyway, I need to do some more thorough testing overnight, but it looks like she ain't gonna hit 2.7GHz

i've not tested any temps on mine yet, whats the best thing to use to check temps ?

BIOS is most accurate IIRC.

Running mine @ 2.2ghz and there's tons more room left. This is with stock cooler, 1.5125v, 34 degrees. Prolly don't need that much voltage so i'm gonna have a bit more of a play next time i restart.

[shiato storm]

cool, mine came with the stock cooler 'cpu in a box' thing...so should be able to get some good use out of it...i'm guessing its the same fan supplied right up to the 3500 and maybe beyond so should be capable of withstanding a bit of increased juice through the cpu

[Butcher]

BIOS, MBM, etc are usually +/- ~10C or so, if you want accuracy you'll have to pay top dollar (as it were) and get a thermocouple based temperture meter.
