The Opteron Skt 939 Overclocking thread !!!!

[megatron]

If u dont have the cold bug I would feel confident that phase will give a better overclock than aircooling.

**Cough**

I think Kyo might be refering to these:

And not these:

So no cold-bug issues.....

Just a quick pic of my results on a CABYE 0540 FPBW
SuperPi 32mb stable, Prime stable >24hrs, now (finally!) 3dmark stable!
Cooler is Arctic Freezer Pro, memory is 1gb GeilONE

I'm certain the cpu will go further but the htt seems to die at anything over 280 on this abit av8 bios24

Your absolutely correct. Been told rightly that they may not be proper phase coolers but i take it in your opinion their better than conventional air coolers like TT or other similar coolers?

you should get a better motherboard... my 146 0540FPBW does 10x307 prime95 stable, 10x313 spi1m stable, and 10x320 screenshot...


kyo: it's essentially a heatpipe heatsink...

 

[sniper007]

Only just got my opti up and running. Had a v quick play yesterday morning and managed to boot into windows @ 2.83 ghz @ stock volts. This is with the crappy stock AMD heatsink as well. More volts and tweaking could bring some good results Im hoping. Will have more of a play this morning.

 

[y2w2003]

got my opty 146 cab2e @ 2.8 with the artic freezer 64 pro and on 1.45 volts. But it's not prime95 stable even though there have been no problems elsewhere. I'll try increasing the voltage a bit to see if that does the trick. I'm on an asus a8n-e board.

Guys can anyone help with my problem in post #1713 please

And when you guys refer to Prime stable to you mean Small FFT, Large FFT or Blend?

Cheers,

Suman

 

[bigwhoppa]

i usually run it on a blend.

 

[Sumanji]

And does everyone running a DFI board have the extra molex and floppy power connector plugged in? I haven't bothered with those...

Cheers,

Suman

You're confusing the fact that Vapochill manufacture 'proper phase-change' cooling units (see the image of the large box with the tube coming out of the top a few posts up) as well as regular, air-cooled heatsinks (such as the Micro).
The Micro isn't a 'proper phase cooler' nor any kind of 'phase cooler' at all and would never be marketed as such.

To answer your other question, the Micro is reported to be a fairly decent performer let down by an overly fiddly mounting system.
It's not really competitive with the latest 120mm fan-capable Thermaltake/Thermalright/Zalman/Scythe heatsinks though.

@ Sumang007 I have an epox 9npaj sli and use a 20pin psu on the 24pin socket and plug the additional 12v connector in since my psu is supplied with it. I think its to spread the load through more wires, meaning each wire will be less hot.

@ Nightic The last time I read a review of an aircooled TEC cpu cooling device, it wasnt any better than a plain air cooler. There is a good reason for this too. The TEC or any kind of super cooling brings with it lots of inefficiency.

I have read there was a problem with the 704BTA non-official BIOS regarding the memory divider issue, not sure if it still exists but I'd definately try to stick to official releases only to reduce risks of unforseen problems.

Normally when people refer to being Prime stable, they mean Small FFT as this stresses the CPU to a higher degree than the other options. Might want to note SP2004 implements an old version of Prime so I'd advise getting the standard Prime95 program, version 24.14 and running a Custom setup of 8-4096 in the testing options, this should really push your CPU more than any of the others.

 

[Sumanji]

matt1: Don't suppose you could point me in the direction of a 623-3 modded by BigToe?

[edit] Reason I need Big Toe's is because I'm running my RAM in the yellow slots, and official BIOSes throw a hissy fit at me during POST, telling me to put the RAM in the orange slots for DC.

Guys I'm really confused and I have quite a few problems... bear with with me:

1) Neither CPU-Z nor Clockgen can read my memory clock when using the 140 divider... is this a bug? MemTest86 seems to think it's running 1:1 at 280Mhz (it's definately not!) Only 3DM'01 gets it right!
2) Related to this, it seems using the 140 divider automatically disables 1T for me and bandwidtch takes a massive hit (see Sandra). Is this a BIOS bug?
3) Apparently my memory is running at 194Mhz, but how is this possible?? 2800/194 = 14.43 and I thought A64 could only use integers as dividers... shouldn't it be using 2800/14 = 200Mhz?!

Cheers,

Suman

Hello Mate
I have a DFI Lanparty NF4 SLI-DR and the same cpu and get exactly the same problem so i am guessing this isnt a error that just you are getting.
I run a 150 divider at 285 X 10.

cacje 0546bpmw

After waiting 4 weeks my 146 arrived today, i have been wondering whether I would get a cabn or a caby or a cabg, etc and I have got a cacje 0546bpmw.

I can't find much information about it and as my other parts for my new pc don't arrive until Monday evening(12th) I can't do any testing.

If anyone has any information about this opty I would be grateful

 

[sepulchre]

I'll be getting my new PC built just after Christmas, already I have a DFI LanParty UT NF4 Ultra-D and a XP120. Coming in the post is 146 CABYE 0550. I'm a little concerned my overclock will be limited by the ram which max's out around 200FSB. Any idea what OC I should be aiming for given the poor ram?

Cheers.

 

[matt1]

That's the first mention of a 0550 week, neat.

Suman here's the major DFI BIOS thread thread . Not sure of that specific BIOS you want, might email him and ask politely

200FSB ram is what I use. I use 300HTT * 10 = 3Ghz, and a 2/3rds ram divider (133ram) for 200Mhz. I have used 250ram but after stress testing it failed to post at that again. TBH, when I ran at 150ram I didnt notice the difference, only the size of ram you can tell. Especially with 1Mb ram l2 cache and 16Mb lv1 cache of on cpu.

 

[sepulchre]

Megatron, OK I see what your saying, I'm hoping to hit 3Ghz with this chip but I was concerned that the ram would hold me back. Good news then Cheers for the reply.
