Worst clocking chip ever!

I bought a 939 venice 3800+ and even running it at 2.6 gig (220) fsb it is still not stable, EVEN WITH 1.71 V CORE!

Memory is fine. Tried it at 250FSB with a multiplyer of 10, refuses to boot. Loathed to put more on the VCORE as I don't want to melt the chip as it's on air.

I have a DFI Lanparty RDX200CF-DR - any suggestions?

Thanks.
 
well if you can't get 2.6ghz with 1.7vcore then cut your loses and move on. That is indeed pretty awful. Having said that, if you can get 2.5ghz at 1.5vcore or less.....that wouldn't be too terrible.

Personally I'd look to find a better chip. And I really don't think that you should put much more than 1.55vcore through any AMD 64/X2 unless you've got water cooling.
 
I would hasten to say that its so unstable as it would be getting far to hot. 1.71 volts (imo) is too high even for high end water let alone air.

Some of the venice chips were just rubbish overclockers regardless of what you do to them. although it is odd that it basically won't overclock at all.
 
1.7v is fine for a while, i caned my 3000 with 1.8 for a bit, my x2 has had that treatment as well.

You need to have a high cpu voltage when youre using BH-5 t
 
The chip is one month old. I now have finally got it stable by running the memory at 166 and not 200. Temp wise the motherboard reports 50 degrees, that is after a lengthy session at Rainbox six Vegas. Not sure how to alter the HTT on the DFI board, anyone know how to to that?

Oh and 2.4 is standard for these chips.

Thanks.
 
Ok update. Got it stable at 2.7 gig, HTT x4 225 FSB 1.525 Vcore, memory at 180 FSB. I think that is all I am going to get. Is that a poor overclock?

I had an identical problem with my Athlon 4000+ on an epox board using the same Corsair Ram which would only run stably if set to similar settings to yours. I swapped out the memory for 2 gb Patriot low latency and my problems vanished.

No, more like a poor overclocker ;)
 
Im getting 2.5 stable on my 3200+ chip at stock volts, the way i found that it worked was also running the memory on a 166mhz setup, and 250x10 on the core. The hypertransport is at 980mhz. Yours wasnt exceeding that during the unstable period was it, as that is, im told another reason 64's get upset.

Im on a cheap ass ECS A939 Nforce3 board atm, but have the same DFi board for when my wallet fills enough to get a X1950.

My old Opty 146 hit 2.5Ghz on stock volts, and hit about 2.8Ghz if i up the voltage a bit to 1.35-1.375. At which stage my mobo begins to crap out i think due to overclocking the HT, 280x3=840... my NF3 250Gb chipset is rated to 800Mhz HTT IIRC, and dropping the divider to x2 gives me boot probs.

Not amazing for an Opty, but ok for a first time OC (40%).

oh, and for reference, best A64 OC guide i've found:
http://forums.guru3d.com/showthread.php?s=&threadid=139322

great explanations of HTT, FSB, Mem timings, ect.... designed for DFI boards, but works for others too!
 
I have my system in spec...once I hit 2.65Ghz, regardless of voltage, it never seemed to
A) Want to go stably further or
B) Would work fine, but then on next boot, would refuse to boot up, so would have to restart with a CMOS clear etc


Anyone got any suggestions for that or is it just a poor clocker?

Im using an AMD 64 Freezer Pro cooler btw.
