Cant get past 168 FSB

All i could get stable with 2x256 pc 3000 hyperX on my new A1 stepping is capable of 180 mhz MAX...i replaced an old A3 stepping board with the same ram was running stable at 200 and would post and boot up to 208 fsb. The ram and the A1 stepping is the problem...some kind of imcompatability of voltage issue on the new boards i dont know what else to say.

I Ordered 2x256 pc 3500...because philip is running with that combo and the A1 stepping @ 231 fsb. So now im praying i get some sticks that wont mess up. I really dont want to RMA this after taking a hit on RMA and restocking fee on the previous a1 stepping board i ordered thinking for sure it was the board.

just to add some info, i have kingston pc3000, 1 stick of 512 and 1 stick of 256 running in dual channel(i have the newest bios also) and right now i'm at 9.5x200 at 2.7vdimm and 2-2-2-4 and it was stable running ut2003 and superpi at the same time for half an hour(that's all the time i had). i will try more stability testing tonight or tomorrow and let you all know. good luck with the problems and i hope that i don't run into them(although my cpu seems to be a bum).:D

I cannot get to the Epox site at the moment, can you post the e-mail address? I want to ask them about the single channel vs. dual channel as this seems to be the major issue.

Thanks :cool: It just doesn't make sense to me cause the board is rated to 200mhz. The new bios gives it auto-detection for the new 200mhz (400mhz DDR) Barton's that are coming out, so they will be added to the specs. If someone drops a 200mhz FSB Barton in there with 512mb sticks of Kingston, you will not be able to run the Barton at it's rated speed, you will have to back down the FSB LOWER to like 180mhz (or have to run the mem out of synch with the FSB which is a huge performance hit). All our proc's now are 133mhz, so that would be like having to run them at 113mhz. Nobody would do that and nobody would use this board if that were the case, it's BS man.

Anyway, the email is [email protected]

I haven't heard back from them since my second email, so I'm getting the blown off feeling. Plus Kingston just called me this morning to tell me they're out of stock on my RMA https://www.sharkyforums.com/ so that blows.

Are you synched with the FSB?

UPDATE:

Epox emailed me back again today. They don't know if it's incompatibility or what, but he said he forwarded it on to "HQ" for review. See what that does (where did I put that rooleyes smilie... :D Hey, you never know). At least we're on the same page now. Now it's up to the rest of you guys to email them so they know that lots of people with kingston 512mb's are having this problem. Here's the reply:

Jason, Sorry we had some confusion on what you were trying to accomplish. I've emailed our HQ to see if they have any kind of resolution or if it's straight up incompatibility. We also can't discount it being on the Kingston side - something that was a bad batch or is fixed in a later production run of the chips.

Hey thanks again. FYI I've emailed Kingston about it as well, but they haven't emailed me back yet, so shame on their tech support, kudos to yours :) Please let me know when you hear back from HQ.

Just wanted to give you guys an update on where i'm at.
After an hour or so on the phone with Epox, and trying their beta bios, nothing seemed to work. Then I changed my CPU interface to optimal from aggressive and I'm now at 8x190. I will try to go up further once I run Prime95 and memtest for a while longer.
I'm not sure if this is something everyone already knows, but I just thought I would share it.

I wonder if it will end up being Epox blaming Kingston and Kingston blaming Epox.

Yeah I tried the optimal to aggressive as well, still same result for me, at least you got a little higher. The only other thing I can think of that I haven't done yet is check the contact my Vantec Iceberq has with the NB. I know the NB is concave, so I put some extra Ceramique on there, but I haven't checked it. Gotta take it all apart cause I need to get to the clips from underneath the mobo.

UPDATE:

Epox emailed me back again, said they would let me know when they hear anything. No new info, but it's nice to see good response from the tech support people. Just an FYI for everybody as to where we are at. Their reply:

Jason, As soon as we get any information, we'll keep you inform.

wow didnt know epox was up to par like that with their tech support. Really nice to hear about such fast responses.

yeah, i'm in sync with fsb but i eventually had to lower it to 2-3-3-6 at 2.7vdimm. stability however is not fully assured yet.

Well, I did e-mail Epox and got the stock response. Quite dissappointing actually and I am too tired to reply at the moment.

Thank you for your interest in EPoX products. Unfortunately overclocking issues
are beyond the scope of items we can provide technical assistance for.
Overclocking is done at the user's own risk. Overclocking has the potential to
overheat processors, create stability issues and other problems not present
during normal usage. We do not endorse or check the reliability of products with
overclocking.

Thank you for your understanding.
