Memory fails when 'limited' in BIOS to it's rated speed

post #1 of 12
Thread Starter 
I'm about to try my first overclock and am already having problems with my RAM. I'm using 2x512 of Kingston Value RAM DDR400. I know the ValueRAM isn't good stuff, and I would have gotten something nicer if I'd known at the time I'd be trying to overclock. The same goes for the motherboard. It's a socket 754 (blech) Asus K8V SE Deluxe. I don't have high hopes for the overclock, but would like to get my Athlon64 3200+ from 2.2 ghz to at least 2.4 ghz. Anyway, back to the problem at hand.

Since I've had this mb, the BIOS has been set to Autodetect the memory speed. Yesterday, I set it to limit to 200mhz (DDR400) and it would not boot. I had not overclocked ANYTHING at this point. What could be causing this? I'm very concerned that my memory is not even performing at its rated speed and this is going to completely eliminate any hopes of overclocking. CPU-Z does show PC3200 RAM in both DIMM slots. What am I missing here?

EDIT: Apparently CPU-Z never did show the proper speed RAM when both DIMMS were installed.

There's a chance you have 1 or for that matter 2 defective sticks. Don't be alarmed your memory has a lifetime warranty (all memory does) so you should be able to get it rma'd.

What you want to try is 1st keep your Memory speed at DDR400, and take out one stick having 1 stick in the blue memory slot, and see if it boots, if it does then try the other stick in the same blue slot as you tried the other, and see if it boots, if it does, then chances are its a problem with your memory slots or the motherboard itself.

Try different configurations after that, for example

Quote:
[ Used | Used | Empty]
[ Empty | Used | Used]
[ Used | Empty | Used]
and so on...

by the way, your board isn't a bad board, actually its pretty good other than the fact that its got a VIA chipset, you should've gotten the Asus K8N Deluxe which has an nVidia nForce 3 chipset. Your processor is fine, they've made boards for 754 socket processors that help future proof it, for example, the EPoX EP-8NPA SLI is a 754 socket board, but supports SLi (PCI-Express) which should be your next upgrade when you decided to get another / better videocard. And valueram isn't that bad either, my friend got a 800MHz overclock with his intel (3.0 > 3.8) cpu on ocz valueram, and ran 2.5-3-4-7 timings which isn't that bad.


BTW, go to User CP, and edit your System Specs.

The secret to the K8V Deluxe is running a memory divider.

It's an unlocked board, meaning the PCI/AGP frequencies increase as FSB increases.

KVR is also limited to ~216 FSB on stock timings (didnt have any luck loosening them either)

So the object is to keep your temps down, run higher FSB, and pick the appropriate divider to keep the memory at or below 216.

One thing is for certain, K8V Dlx's are extremely picky

Thanks for the quick responses. After looking through my motherboard's latest manual online, it looks as if it may be as simple as changing the configuration as Lightsource suggested. When I built the machine, I first had the RAM in slots 1 and 2, but for some reason it was unstable. It would run for 5 minutes or so and just freeze. I changed this to have RAM in slots 2 and 3 and it's been rock solid ever since. Well, come to find out, the latest manual says that the max speed with double sided DIMMS in these slots is DDR200. Crazy, because I know I'm getting faster speeds than THAT. Anyway, as soon as I get home, I'll try slots 1 and 3 as the manual indicates this configuration will support DDR400. I just hope the problem isn't with slot 1 since my first unstable configuration was the only time I used that slot. Thanks again for the help. I'll keep you guys updated.

Right, so I come home, open her up, take out the memory and install one DIMM in slot one. Boot to the BIOS and limit it to 2:1 (DDR400). Boots fine, runs fine, everything seems dandy. Power down, swap memory sticks, putting the other DIMM only in slot one. Same results. Everything seems ok. In both these cases, CPU-Z reported memory frequency of 200 mhz. I power down, leave the first DIMM in slot one, Place the second DIMM in slot 3. Now it won't boot, screen goes black. Power down, place the second DIMM in slot 2. Will not boot (tried this limiting to DDR400 AND Auto-detect speed). Power down, DIMMS back to slots 2 and 3, doesn't boot off the right hard drive, apparently BIOS has been reset to default settings. Reboot into BIOS, set things back how they were with RAM limited to DDR400. Reboot through windows logo, screen flashes blue and computer reboots itself. I go back into BIOS, set to auto-detect memory speed, and system is back where it was yesterday. Nice and solid. I check CPU-Z to find my memory is running at 157.3 mhz. What's that? DDR314?? I guess that's as fast as it's ever been, but I have no idea why. If both of the memory sticks will work at DDR400 alone, what can I do to get them working together at this speed?

I need Help!! thanks guys.

First: Verify that both ram sticks have the same part numbers.

Second: Verify that CPU-Z registers the sticks identically (one stick at a time, in the blue slot). The SPD tables should be the same for both sticks, as should the model numbers that cpu-z reports.

Third: I just checked my wife's rig, she has 2x512 of KVR in her K8V Dlx. One in the blue, the other in the yellow directly adjacent to the blue.

Both RAM sticks have the same part numbers. They came together in the same package. CPU-Z does show identical numbers in the speed tables, including timings of 3-3-3-8 at 200 mhz. The only difference between the 2 DIMMS in CPU-Z is the serial number 8602BF46 vs. 8602BD46. I just don't get what's causing the problem. Is there some memory controller setting in the BIOS that I've missed??

Xavier,

Can you check and tell me which BIOS version is running in your wife's computer. I've been searching the ASUS forums, and apparently the board is crazy picky about memory types. Though KVR is qualified for the board, others have also had issues getting it to work in different configurations. Some have solved their issues with a BIOS update. Since your wife's computer is doing exactly what I need mine to do, I'd like to try to match my BIOS to her's if possible.

Thanks for your help,
mark


edit: Also, I just realized how outdated my VIA chipset drivers are. What are the chances that updating these will help the mb to recognize the memory correctly ??

Bump ....


Did you get a chance to check that BIOS version??

FWIW Asus tech support is absolutely useless. I described my problem in absolute detail including which configurations worked in which speeds and what processor I was using and they replied that my Intel processor would change the bus speed of my RAM. Even included the mobo model number in the e-mail header as if they believed I could actually use this mobo with an Intel processor.

Try calling them directly, I think they've got a template for help suggestions rather than actual humans helping.
