**The ASrock 939dual-SATA2 (ULi M1695) thread**

hum, just been trying to load an os onto my new htpc, windows couldnt seem to detect or use my sata drive (but the asrock bios could), after countless hours I found the sata cable that came with my dual sata to be the offending component.
Damn thing wasted a lot of my time and I nearly smashed my hdd

So are you saying that the "official" BIOS has the 274 HTT cap removed? Anybody else got higher than 274 with 1.8 BIOS?

Just noticed the 1.60 bios version that was flashed to my sata2 from the factory can run upto 300htt anyway, but only a max of 1.45 vcore. my 146 only needs 1.4volts to run 3ghz so I think this bios maybe fine for a decent overclock, will soon see.
1t seems fine with the right dram settings to.

I thought 1.60 was locked too?
 
Okey dokey.. now my new system is up and running and seemingly stable, it's time to tweak it's nipples and kick it's ass.... so following the hints from other pages in this thread I've taken my

A64 3700 San Diego
Zalman 9500
1gb Corsair Value Select DDR400

and I've changed the following settings:

Overclock Mode = Async
CPU Frequency = 240
Mem Clock = 166/333
CPU NB = 800
NB SB = 800
Cmd Rate = 1T, everything else to Auto

CPU Volt is still at 1.400, as high as it can go in BIOS 1.8?


My CPU-Z now reads...

cpuz_oc_mem.JPG


That's chopped my Super PI from 40s @ stock down to 33s, and it still seems to be running at decent temps.

Presumably I should just keep ramping up the CPU / HTT until it stops working correctly, and then back off a couple of notches? I'm guessing I should be able to take everything up until the memory is at 200mhz (or a bit beyond if I'm lucky with the particular sticks of RAM), but are there any other limiting factors? The AGP port for instance?

Are there any other setting I should tweak? Any other benchmarks I should try? And where are the best places to go for comparison scores (to make sure I'm getting the right results)?

Any help for this n00b overclocker much appreciated ;)

It is on mine, I've got the 1.8 bios on a floppy ready to go, just waiting for more confirmation that it will pass 274. I get the dreaded cold boot issues with mine using one of the OCBeta bios's, so had to give up on them.

Flashed 1.8 over the weekend and it does go beyond 274 . Am currently at 280 and counting (boots at 290 but not totally stable). Opty 165 now at 2.52Ghz. Hoping to get stable at 290 then I might call it a day. :)

The Asrock Bds seem to set a max voltage about 0.1 above the nominal for the chip. Seems to be a not very well documented optional feature of the AMD 64 chips, probably because of the wide range of voltages that these CPU's have used, from Sledgehammer through to SanDiego.

That's chopped my Super PI from 40s @ stock down to 33s, and it still seems to be running at decent temps.

There is a setting to fix the AGP/PCIx slots at nominal, can't check it at the mo I'm at work, but someone will remember it.

Drop the CPU multiplier a notch or two so as you increase the HTT the CPU is not being asked to go too fast. More HTT for the same CPU speed equals more memory bandwidth, equals more performance.
 
This motherboard with OCZ 2 x 1gb 3200 Platinum. Running at standard settings , 2T.

Anyone else run this combo ?

I'm having trouble getting my system 100% stable. Have tried a new CPU (was 3500 now a FX-60) and even RMA'd the motherboard and got a different one.

On 1.6 Bios currently.

System is memtest stable, but fails Prime blend test, the one that uses a lot of RAM. PC just appears to shutdown, monitor goes off, yet fans still spinning.

Games do appear to be stable however.

Any other people with the same kit running OK, or indeed have similar problems.
 
Malcolm - thanks for those hints...

I *think* the setting you're referring to is the Overclock mode - the options available are Auto / CPU-PCIE Sync / CPU-PCIE Async

I've set it to Async, but I'm not sure if it applies to the AGP too.

You might have a setting for memory compatibility mode in your bios (it does on my board), turning that on caused exactly the same problems with my machine, after turning it off though it was rock solid.

Interesting, i'll try that out.
 
memory compatibility mode?

I couldnt for love nor money get my board to run 1t initially, I knew my cpu mem controller was capable of over 280mhz at 1t and my cheap value ram which im using for this media pc is good for 220mhz 2.5cas 1t. after lots of bios messing I simply switched the ram over to the black slots and it passes memtest and stability tests error free.
 
I have 2 gig of Gskill 3200 zx and it crashed 1t when i try and copy and paste something. Is there any big deal though? I mean surely your only talking miliseconds in real world performance?
 
Just to follow up here.. I just flashed to the new bios p1.80 and it appears that 1T is working for me now. I have treid copy and pasting screenshots into paint and it works, also it has passed prime 95 and super pi. Gonna try memtest as well. :)
 
As a follow up to my posts, I've had to back-track to stock speeds (with the exception of 1T which my RAM seems hapy at). The reason - Super PI ran fine but 3DMark05 crashed. I tried raising the HTT further, but backing off the RAM speeds and CPU-NB and NB-SB speeds, but my system was even more unstable then. Maybe I've just been unlucky with my CPU or RAM, or more likely, I've not set it up correctly yet!

I found getting the memory to run at stock again was tricky - it insisted on running at 130mhz until I changed some of the settings from Auto to manual. Not sure why...

I'll have another go tonight perhaps. But my pc was running well at stock anyway last night, so I'm happy even if I can't get a good overclock.
 
My ram at 1T just passed 30 mins of memtest with 0 errors. Thimgs are looking good, gonna try some more overclocking now. ;)
