Sounds PSU related. What are the specs, i.e. Watts, Amps on Rails, etc :)
Click to expand...

jeantech 450watt

2x 12v rails

14amp on one and 15amp on the other

also this psu has a dedicated pci-e outlet would the ampage be different using this then using one of the standard 12v outlets (i e the disk connectors etc)
 
Yep 939 CPUs. I was asking because some 939 A64s (E4 or E6 stepping 3200+ I think) required a bios update. The 185 is 2x2.6GHz with 1MB per core - equivalent to a multiplier locked FX60 but prices are coming down in a few places - so much less money.

Guess I was asking if they need a BIOS update rather than if they were compatible.

450W would be at the margin of running a system with a x1900xt. What else do you have in there? e.g. many hard disks would be real a drain (see here)! Also, is it possible to get a hold of another PSU, 450Ws or more & testing with that?

Anyone know if Opteron 180 and Opteron 185 are compatible with this board. The ASROCK BIOS page doesn't list them.

will work no problem, both the 180 and 185 are E6 stepping just like any of the other dual core opterons which have been supported since the 1.40 bios.

i cant get hold of another psu unfortunately but i have given the card to a mate tonight who is gonna test it in his rig

and all i have in the pc are 2 sticks of ddr400 geil value ( 1GB total )
one sataII hdd a lan card as the lan out of the mobo is borked and an audigy 2

basicaly all the pc is used for is gaming i got another pc for everything else but it has a smaller psu 400watt

thanks for the link i tried it out and all i need is 304watts!!!

right thought i would give the latest bios 2.30 a whirl. so far its seems to be very good, it seems to be stable at 300htt now for me. pc been on all night running snm cpu test and no problems. usually if i set htt to 291mhz snm usually fails in under 5 mins.

looks like i can't keep my ram timings of 193.4mhz 2.5-3-3-10 which i was using at 290htt. at 300htt have to back down to 200mhz 3-3-3-10 although iv just broken my super pi record so either way its gone faster now. guess the increase in ram clock outweighed the loss of speed from dropping the cas down a notch.

very odd though, fully stable at 2950mhz at 1.40v but to do 3ghz i had to max out the vcore to 1.450v. could be reaching chip limitation now or board could be being silly buggers.

will carry on testing for another hour or so and see how things develop. either way bios 2.30 is the best for the asrock board. for me that is.
 
Just out of interest, why does my sata hard drive show up in BIOS as an IDE device?

Fist one is my dvd writer.

Erm just noticed, one screen shows my sata as IDE, the other is showing my slave IDE, but not sata

Confusing :confused:

have you tried setting a Burst Rate of 2 ? That setting got my 3500ll memtest stable in 1T.
Click to expand...

Well, had a play and have put the ZX back in, setting burst rate of 2 allows 2-3-2-5 @ 1T, memtest passes fully.

Setting the burst rate to 2 with the HZ wouldn't allow memtest to run at all.

All in all it's proved quite interesting, the ZX running at 200MHz is faster than the HZ at 250MHz and all becaues of the tighter timings.

As a comparison;

HZ - Cas 3, Tras 8, Trp 4, Trcd 4, Trrd 2, Trc 10, Burst 4 beats, MA 2t, 250MHz
ZX - Cas 2, Tras 5, Trp 2, Trcd 3, Trrd 2, Trc 8, Burst 2 beats, MA 1t, 200MHz
 
Well, I asked ASROCK about the Opteron 180 and 185.

Here's the response:

Dear Sir,

Sorry, this motherboard does not support these two CPU.

Please refer to our CPU support list: http://www.asrock.com/support/CPU_Support/show.asp?Model=939Dual-SATA2

Thanks for the email.

Yours truly,

ASRock


Unsure whether to believe them or not (they're not a new core revision or anything). If anyone has tried it I'd appreciate a definitive answer.
 
I knew someone that ran an ACB2E 0548UPMW stepping 185 opty on a dual sata II board with no issues, most the 185 batches of cpu are early fx-60's anyway.
I've run dosesns of opterons on my dfi board and dfi apparently don’t even support the opteron range of chips.
Basically the guys at asrock are saying don’t expect support if it doesn’t work, they don’t say it won’t work.
 
This is odd...

I'm fiddling with settings for more overclocking (of course). I think the instability I had with my last settings was a result of trying to run my cheap old Crucial CAS3 PC3200 too fast. So I'm temporarily running it at 2/3rds (DDR266 in the BIOS) to see if the system is stable. It is, but the figures don't seem to match up:

HTT base speed setting: 270MHz
Memory speed: 173MHz

It should be 180. Curious.

I'm going to push some more. If my CPU is stable with a 50% overclock (i.e. 9x300), that'll solve the memory speed issue :)

EDIT: No such luck. Stable at 9x275=2475, but starts getting unstable above that. Memory now at 178, and overall performance is slightly lower than before I started fiddling, due to the drop in memory speed.

What I need is a 3/4 memory setting.

That crucial RAM's great for stability at stock - same stuff I'm using and really reliable stuff - but I've seen people have problems with just a few mhz overclock.
 
Yeah, but I'm stuck with a huge underclock (178MHz) or dropping my CPU speed. Pants. Not enough memory dividers on this board - a 3/4 divider would be almost perfect (that would give me 206 on the memory, which I know it can cope with).

Maybe I can make the memory timings much tighter at 178MHz and offset the lower speed...

People ask me why I'll spend several hours fiddling with settings for a performance increase I will only ever notice by running benchmarks.

Because it's fun, of course!
 
Just put my mem at 1T and windows seems to be fine.

What are the tests i can try again that normally gave bugs with IT? I've tried th copy/paste into paint and it wors fine.

Mem also set to 2beats.
