Ok I recently had problems getting my mobo to run with my pc3200 ram. I changed some stuff in the bios and got it to run after inserting my 2100 sticks to access the bios 1st. Thing if my pc would just restart outa nowhere.
Anyway Im sure i didnt have the settings right.

My question is.. What are the settings i should have in the bios for 3200 ram? i dont wanna overclock it. I just wanna know what the defaults are so i can change it to that in my bios.

Im currently running my 2 sticks of 512 3200 ram at 2100 speeds along with my 2100 sticks ( its the only way the ram will work ). THe only way i can use the 3200 by itself is when i change stuff in the bios.. but that didnt work out well, like i mentioned.

Please help.

well it depends entirely on what your cpu is. Your motherboard will be able to handle any of the default RAM frequencies.

do you have any info on the make/model of those PC3200 sticks?

I'm not 100% sure on the setting in the bios for the IS7 but I believe you need to set the DRAM ratio to 1:1 so it is in line with your FSB. Look in the "Soft Menu" section in your bios.

can you post a CPU-Z screenshot of the memory tab?

I set the ratio to 1:1 and cas latency to 2.5 then the next thing to 5 then 2 and 2. It now boots up with just the 3200. Thing im worried about is that last time i did this my pc just restarted outa nowhere.

But this time i raised the ram voltage to 2.70.. mabey that will make a diff idk.

Anyway. Do you think those settings will be ok? Or is that bad? haha


IM noob =(

ok got it now. After reading all the stickies and what not i figured out what is what.

I now have the ram set to 2.5, 3, 3, 7.

It runs fine and boots up by itself without the help of the 2100 now. I also realize that 2.5,2,2,5 was pushing it haha.

Anyway i shouldnt have any problems now. If i do run into anything ill just change it to 2.5,4,4,8 or something.

Thanks for the help.

run memtest to ensure that the ram is not producing any errors running at those timings. You'll need at least a good 6-8 hours to verify that the ram is stable, longer is better but I would say 6-8 is minimum to call the memory stable.

I was just about to suggest that you back off that 2.5-2-2-5 just a tad but I see that you worked that out on your own.

It is always better, from the stand point of learning stuff to struggle with something and then to figure it out, versus having someone tell you "do this and do that" and then you blindly just doing it without having a clue as to why.

Good job in figuring out your problems. And you're right, if you continue to have reboots, either up the ram voltage a little bit to see if it will help with stability, or raise one of the "3"s at a time until you get stable.

I would suggest, if you haven't done so already, to download a copy of Memtest86+ and test the memory before you actually go into Windows as unstable memory can corrupt your OS. Here is a link to the site.

You slipped your post in there while I was looking for that Memtest link. :)


If you should need help in getting started with memtest, the following link has some step by step instructions (ok, yes its a "do this and then do this" kind of thing) on making a bootable disk or cd, depending on your preference.

Thanks guys.

Yeah ill get on that memtest thing soon. Honestly im lying.. i probably wont do it at all. Lets just hope my pc doesnt blow up or something after 8 hours haha.

don't worry the most that can happen is your memory is unstable and might produce errors, 2.7 volts isn't much, most can do about 2.8 or 2.9 without problems if there is just moving air going over it. Also lowering your timings is just a way to get more outa your memory by lowering the speed that it communicates with your motherboard basically, and as long as it's stable all is good.

You might just want to get Prime95 and make sure it will run overnight w/o crashing, It stresses both cpu and memory to an useful extent.

The IS7 is a high performance piece. Definitely max out the Vdimm (2.8V or whatever it gives you), and max out the AGP voltage to 1.6V or more if it will do it.

The real speed is in the GAT settings. You've worked out the timings, now see if you can run some GAT. The first setting is the main one, with the default "auto" turning GAT off. Try setting it to "Turbo" and see if the system is still stable. If it is, it will be faster. Make sure to disable the last two GAT fields (something I've forgotton, and CPC)--they cause instability in most combinations.

Just hope you don't have anything real important on that PC, or if you do, hope you've got it backed up somewhere...seeing that you don't REALLY know if its stable or not.

Good luck.
