Abit IN9 32X-MAX WiFi & Corsair TwinX DDR2 XMS2 Dominator PC8500

Cool cheers for that - I figured it was something like that. Seemed stable enough, i gave it a good test with 3dMark06 for a few hours without any problems. I am re-installing Vista though, and get the dreaded BSOD. Read on other forums you have to remove 2 of the 4gB, apply all updates etc than re-install.

Don't suppose anyone has read of a way of doing this within Windows XP? ie. Apply the Vista update without removing the RAM? I have my machine dual booting...

-message removed-

I have 4gB running stable at 533mhz. Is this really the fastest this RAM will go? My 3dMark performance has dropped 500 points and Vista Performance RAM speed from 5.4 to 4.8!

I'm afraid of cranking the RAM speed to high - will it blow them? Can I run it at 1066?

it is running at 1066, it could perhaps go higher but pc8500 isnt even an official rating of speed so all they do is make sure it can be overclocked too 1066 normally. Just make sure you dont go over the rated voltages and iot will be fine, 2.1v i think is the limit(check the box etc)/

Hi there,

The Memory DD2 Speed in the BIOS is set to 533. NIB Strap CPU As PSD1066. The Estimated DD2 Data Rate is 533.3 - which I'm guessing is half what it should be?

Can I safely try bumping up the speed to 1066 and test it WITHOUT damaging the RAM? Is the only way to damage the RAM to increase the voltage higher than what it's rated at?

Thanks!

well 533x2= 1066 so you are running it at the correct speeds, there shouldnt really be a need to up it further but id suggest lowering timings of the ram first as that could be affecting it. Well there is a chance of damaging it from overclocking but its reduced considerably if the volts are not increased over the rated, since its designed to take the heat created from that volt. Depending on the maker of the ram then the warranty could be void by overclocking and by changing volt, corsair allow overclocking as long as you dont put voltages above the rated but they allow 5% +- the difference because al;ot of motherboards dont give out 100% correct and dont have the option for say 2.1.

Hope this helped,

hello i have the Abit IN9 32X-MAX WiFi with C2Extreme 3.0Ghz and i constantly face this problem i cant setup my pc with 8Gb ram.I dont mind the cost i just want to buy ram 8Gb total (4 dimmms of 2Gb each) but i want a solution that works i ve tried bios releases other rams(kingston, princeton) the unit keeps hitting blue screens.with certain memory modules i manage to work i mean to boot Win Vista 64bit but this happens only with 2 dimms of 1Gb each.i have never managed to work it with 4 dimms of 2Gb each(800Mhz).can you give me a solution?i am willing to OC it but i don't know the right voltages for the dimms.i am considering corsair as i see you prefer all these dimms.Pls if someone can help me.

you might want to go to the MAX forum on http://forum.abit-usa.com as there will be more IN9 32X users there.
if you don't have your RAM voltage right that could be the problem plus with 4 DIMMs you probably need to increase the mch voltage a bit.

Hi guys, my first post here. I use this motherboard and I want to know if you think this RAM would work for it?

CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory

It would not let me post the link because I am so new LOL! You can view it at newegg and it is 109 after mail in rebate.

Hmmm...I can see after reading other posts that it should work fine with the most recent BIOS update.

Hi Mad Cow, yer that ram should work fine with your board. i have the same board with 4x1GB of pc2 8500 dominator ram and all the sticks work fine at 1066. I had heard that overclocking with 4 sticks is limited to 1066...is there any truth in that or was i mislead? can anyone shed any light? i cant try it at the min cuz my processors coolant leaked on my graphics card and now its dead so my rig is out of action until i can get a new card.

and it still did not work at 800MHz. You are defiantly right about the other chipsets as I put my four DIMM's in my Intel MB at work and they worked at 800MHz no problem. How comes our MB's often have a problem with 4 DIMM's at 800MHz when systems like this have 16 slots running at 667MHz.

or

12 slots also at 667MHz

http://www-03.ibm.com/systems/x/rack/x3650/specs.html

Is 667MHz just a very stable speed?

Hi ,

Those timings are they completely right. ?? Double check as you might be able to run 5-5-5-15 or 4-4-4-12 with them @ 1066mhz. It might be struggleing to sustain 1066mhz @ 5-5-5-18. :)
I agree , when buying ram its safer to buy 6400 and just OC it if you want a 1066mhz mem system. Its a rated memory , cheaper and just as efficient.

I had this board prior to my current setup with an 8GB OCZ set. I also experienced problems , but it was my ram would not run. My fix was to overclock the memory to 1066mhz to make it stable ... go figure ....... but it worked a treat. So the board is capable of running at this speed.

Best of luck
