I've just taken delivery of my 146 and this m/b.

Now.. I'm gonna probably get a SL 120 to cool the 146.. will this fit?
Looking at the board I will have to remove the mounting bracket on the board.. will the four holes that remain be good enought to bolt the unit down?
This is presuming that this cooler requires boling down like the SP-97 that I currently have lol.
Also.. does it require a backplate?
Any help will be greatly appreciated :)

If you use the search feature on this thread with the word "backplate, or back plate" it should give you a few hints.

I seem to remember some people having issues with certain hsf units becasue the Asrock has no backplate.

I would *think* that hsf would require a backplate but I am not certain. :(

i dont know why people keep saying this as it is not the right way to do it, if you use that method and you only have 128mb of ram then your pagefile will only be 384mb and where is the benefit in that? the best method for setting pagefile it to make your phisical ram and pagefile equal to 2 gb so say you have 1gb of ram you set 1gb for your pagefile.

reason ive said it is that ive seen it in posts from people who have given decent advice before, no other reason.

and working off that ive never had any problem so guess i was just lucky.
 
need some ideas
i have done the vcore mod and was running fine for the last month at 270x10 1.55v (set at 1.15 in bios)
out of the blue i think the ocwbeta2 bios corrupted - the text went all unreadable and i ended up having to clear cmos, and set it up again. now it will not remember the voltage setting what ever i do and defaults to auto which wont let me get much higher than 250x10

i tried flashing to the 1.50 bios which went well, but it will not remember the voltage setting - i change it to 1.15, hit f10 to restart (which it does) and it hangs on the graphics card bios screen forcing me to powerdown then on again, and the vcore setting is not remembered, reverting back to auto

any ideas as i think some of the previos bios 'shadow' may be there affecting things

help/ideas appreciated
 
Encephalopathy, I posted the same question on this page and if you check the last couple of pages on this thread it seems to be a common problem but there doesn't seem to be a solution as of yet.

I've asked the same question on the OCW forum(as it's the beta BIOS's I would rather be using to break the 274 HTT mark)but I didn't get a reply.

HTH, dagwoood.

I've seen this happen on my board from time to time but it has always gone away after a bios flash. One thing to try, dunno if it will help though, is to flash the bios, then turn the PC off. Move the motherboard bios jumper to the 'clear' position. While it's there, turn the PC on. You should get the system to boot but give a beep error and error message that it can't find any boot devices. Turn the PC off and move the jumper back to it's normal position. Try again.
 
You guys O/C your memory and if so, what advantage do you gain ?
I have the OCZ 1GB (2 x 512MB) PC3200 Dual Channel Gold Series BH5 EL-DDR CAS2.0 (OCZ4001024ELDCGE-K) (MY-054-OC)
in my machine, which seems so far to be working fine. (rest is in sig). now i know some of you O/C your memory but I dont know where to start to be honest. My CPU is running at 2.7ghz opteron 146 on air and that has been fine.

What are the advantages of O/C memory and can someone give me some pointers as to what to change etc or a link to somewhere usefull for this motherboard
 
@dagwood
i have 2x512 geil value and up until the weekend when things when awry they were running rock solid for a month at 230 (ddr166 divider) with the rest of the memory settings on auto

@ns400r - thanks - i had cleared cmos before flashing bios, but not after like you have suggested - will try this as it is driving me nuts

the only other thing i can think of is that i need to redo the vcore mod in case it is only working intermittantly - however i dropped the multiplier way down, set the bios vcore to 1.15 and booted into windows at 1.6mhz - then ran cpu-z and it was reading vcore as 1.55 so i guess it must be ok...

cheers
 
just out of interest are there many of you using the stock heatsink?
the temps are really good, im using MBM is this accurate?
just put it up to 220 FSB and its reporting temps on the desktop at 28 can't beleive how cool these chips run :) yes i know its not much of an O/C but this is my first 64 setup, and there at bit different than the XP cpu, and i'd just like to say that this board is great

check what divider you're running the memory on at the moment, should be ok for 133, maybe get 166 out of it.

what timings you running at the moment, can be checked using cpu-z.
 
i *think* the problem may be that when i set 1.15vcore in the bios it won't load this as it thinks it is too low see http://www.ocworkbench.com/ocwb/ultimatebb.php?/topic/30/6093.html

i will try the vid3 vcore mod next as it means setting 1.35v in the bios gives a real 1.55 and the undervolt protection should not be a problem booting at what the bios thinks is 1.35......crosses fingers

so next question - how do i get rid of the conductive paint i applied for the original vcore mod without damaging the board?
 
it is on 133 at moment, timings are
In BIOS i get there figures:

DDR 1 512MB/133mhz ddr266
DDR 2 512MB/133mhz ddr266

Cas latency Auto
TRCD Auto
TRAS Auto
TRP Auto
MA Timing Auto

CPU-Z under memory tab

Frequency 180.0 mhz
fsb:dram cpu/15
cas# latency 2.5 clocks
ras# to cas# delay 3 clocks
ras# precharge 3 clocks
cycle time (tras) 7 clocks
bank cycle time (trc) 11 clocks
DRAM idle Timer 16 clocks


on CPU'z Under SPD tab,
I can choose slot 1 or 2 but the only figure it gives me are module size, nothing more.


hopefully some of you can point me in the right direction if i needd to change anything to gain more. I dont understand how some of you seem to change the memory voltage, i have not seen anything in the BIOS that seems to do that ?
 
Chef:

Change Dram voltage to HIGH, its on the chipset settings menu towards the bottom of the page.

try the memory clock at 166, if its happy with that try changing the MA timing to 1T, if that doesnt work, leave at 133 and just change the MA timing to 1T.

looking at the timing there seem fairly decent could try working towards 6-2-2-2 in steps, so try variations of 6-3-3-2.5, 7-2-2-2.5, 7-3-3-2 just to see what the memory can cope with.
 
Hi guys...anyone using corsair xpert and got mem dashboard working as mine does not recognise any memory installed and the voltage does not change on the ram either when i change it from normal to high just says 2.7v this is when it scrolls down on the ram itself.
 
ok MP260767 I shall try that.
Must ask this though, when you say things like 6.2.2.2 or 6.3.3.2-5 in what order do you and others refer to them ? is there a set way ? Just trying to understand what for eg: the 6 refers to and the next 2 etc .

So i dont have to actually physically change the voltage myself, somehow the clever BIOS does that for me then ?

Hope to hear form you soon and thank you

Okay, I changed from 133 to 166 and it booted but as soon as I ran SuperPI @1MB it gave an error.

Changed back to 133 and then changed something to 1T and ran SuperPI 1MB again did it in 1second quicker than when it was on AUTO in the BIOS.

Dram Voltage was already on HIGH from when someone on here, told me how to OC my opteron anyhow.

hi,

never really done a vast lot with memory timings tbh as i normally work with different memory manufacturers so jus happy to get it stable :), think there is a memory sticky around that will describe the settings better than i can, sry about that :(

main thing that may help is the CAS Latency see if it will run at 2 rather than the current 2.5.

with the 166 it maybe worth trying it with slacker timings, so going from 7-3-3-2.5 to 8-3-3-2.5 or 8-3-3-3.
 
Slightly off topic but.................


Using Speedfan to control the speed of the CPU fan isn't going to happen.
Suggested to me by Alfredo (the writer of Speedfan) and now confirmed by Asrock.

Dear Sir,

When you are using a boxed version of the AMD cpu then

the AMD CPU fan speed is controlled by CPU fan it self.

Please refer to below link page 8, No.4 for more detail:

http://www.amd.com/us-en/assets/content_type/DownloadableAssets/Cool_N_Quiet_Installation_Guide3.pdf

There is no “fan speed control” function from the mainboard to the cpu, because this is hardware-controlled by the fan of AMD

The BIOS setting Cool&Quiet is for CPU frequency.

When system is idle, the CPU frequency will low down.

Kind regards,

right, changed to 1T, changed cycle time from 7 to 8. as you said MP260767, changed CAS Latency from auto to 2. Now all i see is a second on 1MB superPI quicker, now at 31/32 seconds.

As for me overclocking my 146 Opteron, i left it at 270 in the BIOS as anymore and it wont POST/Boot, i believe this is something due to the P1.50 BIOS im using, it wont allow any higher than 274 ? Anyhow i though i would try typing in 274 in the BIOS and it posted, windows loaded fine, temps at 32*c whilst im typing this out. Seems ok, mind you its only a small increase from 2.7 to 2.74ghz, but i quess every little helps.


Now as for the memory, im still not 100% sure when you guys say 2-3-3-4 etc what each of those figures relates to, what is (2) referring to etc and so on ?

My Memory is in my Sig!

thanks everyone, your slowly making me gain some understading of OC'ing
 
yup standard bios' are limited to 274, ocwbeta 1/2 allow you to go higher than that.

had a look around and found this thread, check it for the memory setting descriptions you were asking about:

http://forums.overclockers.co.uk/showthread.php?t=53160

main section u'll be interested in :

CAS (2.5 or 2) = Lower gives significant performance increase
tRAS (7,6 or 5) = Gives very small performance increase
tRCD (2, 3 or 4) = Lower gives significant performance increase
tRP (2, 3 or 4) = Gives very small performance increase
CMD (1T, 2T or 3T) = Lower gives very significant performance increase
Bank Interleave (None, 2B or 4B) = Higher gives very significant performance increase.


so the cas2 and 1T seem to be quite useful, just need to see what you're system can handle with the tRCD and bank interleave, would suggest reading the link to confirm the details.

I've read that the CAS setting on AMD 64 makes very little difference, unlike the XP Athlons. It is the middle two settings that make the bigger differences
