L4VXA2 CMOS checksum error

[lordkn]

I am receiving the following error and need help to resolve:

cmos checksum error - defaults loaded
Warning! CPU has been changed or CPU Ratio changed fail Please re-enter CPU settings in the CMOS setup and remeber to save before quit.

Need assistance to reslove this issue After Rebooting machine does not post. I have to reset cmos for it to post to give me this message again

I have a Intel pent. 4 2.4Ghz

I had a similar problem with a loose battery.I would always get a checksum error.At least that's a place to look

I'm having the same exact problem with this mobo and a p4 2.4 as well. If you figure anything out, please let me know....thnx

I would replace the battery. Had a new board do the same thing...

Question is where was your post yesturday before I bought this damn thing? Just bought it yesturday, spent the day trying to figure out what I did wrong, Finally I can get Win XP to boot, but only if I clear CMOS JUmper and hit F1 to continue past Cmos error. If I reboot, I have to go through it all again. If I enter bios to make any changes, after save of Bios settings, the only way to get a post is to Clear the CMOs. I guess I shouldnt ever turn this thing off. ECS hasn't been much help. Just out of Curiosisty, what type of Video Card do you use? I use a GFX 5200 PCI.

Okay, got it figured out. Just out of curiousity, did the others out there having probs happen to get it from Fry's Electronics? The problem turned out to be incompatable memory. The board is supposed to be compatable with some 400mhz DDR sticks, and Fry's advertised the mobo and cpu combo along with a DDR 400mhz chip that was supposed to work with it according to the ppl working there. Anyway, stuck 266mhz DDR in and it worked fine.

Yes, it's a memory problem. I had the same problem, and yes, I got it at Fry's. This board will work fine with 333 and below, so 266 should work just fine.

By the way, if you just press F1 and ignore the CMOS settings, chances are it will boot just fine, but you'll still have a problem the next time you boot. In other words, you can use the computer, but need to play with the jumper each time until you get your memory swapped.

The manual explains it, but it's full of weasel words. The specs on their website say "Supports DDR400 (conditional) / DDR333" with no explanation of what is meant by "conditional." The manual says, "we do not guarantee that all DDR400 memory modules will work properly..." They are implying that it most likely will work, but they don't guarantee it, but the truth is it will most likely not work unless the 400mhz DIMMS are specifically designed a certain way.

What bothers me more about this motherboard is that the manual is full of these types of statements with no explanation. After I got home, I found out that words like (optional) do not mean that I have the option. It means that they left it off.

With even the lowest end motherboards out there having two serial ports, why did they leave one off? (actually, the circuitry for it seems to be there; they just left out the port, and did not supply a connector so you can add your own.) Why did they build in a sound card, but leave off the pins for hooking up a second CD or DVD drive? If you have to buy these things later, you might as well get a decent motherboard to begin with.

But the biggest problem is their support. It stinks. Given the text of the manual, I suspected a memory issue from the beginning, so I checked the web for AWARD's beep codes to confirm it. The sustained beep indicates a memory issue. But the folks at ECS don't have a clue. I checked with them to make sure so I can save myself a trip, but they gave nothing but wrong info. They won't accept phone calls. They took a few days to get back to me by email, and gave the wrong answer. It wasn't even in English. (I wrote to the Fremont office.) When I told them that their advice did not work their response was don't ask them. The actual response was, "Please contact your reseller for more detail (sic) help or warranty repair if necessary."

I use DDR333 memory with my ECS L4VXA2, but I still get the error. Also, about a minute after starting up my system for the first time, it automatically shut down on me. I tried turning it on again right away, but it would not boot up. I waited until the HSF unit cooled down to turn it on again, and at that point it did boot up, but once again I got the CMOS checksum error. Anyone know what the problem is?

If you have access to another memory stick, I'd say test it out, this error seems to be memory specific. You might also try a different mem slot. Also ensure the memory meets the very limited specifications given in the mobo's manual.

this board has memory compatibility issues. the problem is, most people who work at fry's aren't that computer-knowledgeable. there was a special on simpletech memory, and i asked specifically if this memory stick would work on the board--the answer was yes. it turns out this board has trouble running at 200mhz dram setting, so i kept lowering it until i got it stable enough, which was 100mhz.

pay 94.99 for that performance isn't worth it, so i returned it for a corsair and a kingston, knowing that both are top-notch modules. the l4vxa2 has trouble running at 200 with both. so my guess is that it will run at 200, but expect freezes. u can, however, lower the dram setting to 166 and it will run fine.

my suggestion is to get a pc2700 or 2100, or lower your dram setting to 166 and wait for a bios upgrade (which i am doing). btw, b/c of its 2.5 cas latency (kingston one is 3) the corsair memory has better performance until memory tests i used.

hope this helps. i like fiddling around with these cheap boards, but they are a pain sometimes. if u want less problems, go with abit, asus, tyan or the like.
