You are so right about Asus' website. Even when you find what you are looking for, chances are that the description leaves you confused (the more current BIOS file descriptions don't even mention EZ Flash)!Originally posted by: computer
It's not a good idea to do it in Windows due to the Windows instability. If there's an error or crash, you're screwed. You always need a floppy; for one, to run the memory diagnostics programs like WMD and Memtest (although they could probably be run from a CDR). Like I said, the flash utility is part of the BIOS file's download. 😉 EZflash info is here . Since I've never used LiveUpdate, someone else will have to give input on that. Asus's site is always so screwed up with bad links and "internal server errors" is useless to search. Every time I try to search for something I get "the server is temporarily unavailable". The SOB NEVER is available.

Which do you mean by "that chip", the Costa?
Well, so far I tested the China at 1:1, the max it handles is 243 with no errors and 244 with one error per pass (standard mode).
It seems to like a little higher vcore (1.5875) but refused to boot at 1.625 :frown:
Will test at 5:4 next.

Fry's does not have any except 2.8C and not sure where they are from.
I do not suppose anyone has an M0!

If the bus is max'd out on the CPU, it wouldn't matter. But if the bus is max'd out on the memory, going to a higher voltage will enable one to get higher DDR speeds from your memory. On mine, going from 2.85v to 3.1v got me about 20mhz more FSB.

Thought I had this memory problem figured out, as I had stated before the system runs awesome with 2 sticks of memory in slots 1 & 2 which are not the same channel. Switch the same two sticks to 3 and 4 which are also different colors, and the system would lock up. Swapped out those 2 sticks with two more and got same result. Replaced the motherboard and you guessed it, same problems. Only thing left is the memory, but it makes no sense to me that they work fine on first two slots but not on the second two. Is there something different with installing ram on the second two?

DRAM RAS# to CAS# Delay. . . 3

Put everything else to defaults except for your Graphics Aperture Size, set this to the max Value of your Video Card (i.e. 128 or 256 etc.)
I would start with these timings, especially if your planning to run 1:1. If you find that you can get all these settings set and run fine then you can start tightening the timings to 2-2-2-6 if it can run at these timings, this memory is actually SPD programmed for 2-4-4-8 but that setting is no good in most machines, so I would start with the 2-2-3-6 as a base and then maximize your FSB as much as you can without error or BSODing. If you find you can't run any of these timings 1:1 then I'd jump down to 5:4 and you should be able to run the tighter timings without a problem or just RMA the RAM and get a good set.
Have you actually used this RAM in another machine or had it tested in such a way that you know it's good? MemTest-86? Windows Memory Diagnostics? I suspect however that even if it checks out ok that due to the speed of your Processor, it's making life difficult. AS I'm sure you already know, most of us who do overclock and have been seeing the results of many different configurations, prefer the 2.4C simply because it's really the most flexible and overclockable of the processors to date. In any case it just means that you have to be more stringent with memory requirements.
Advanced Tab --> JumperFree:
AI Overclock. . . . . . .. . . . . . . . . . .[Manual]
CPU External Frequency (Mhz). . . [216] (This sets your FSB i.e. you may want to run this at 200, then work your way up.)
DRAM Frequency. . . . . . . . . . . . . . [400] (This sets your divider i.e. 1:1, 5:4 and 3:2)
AGP/PCI Frequency (Mhz). . . . . . . [66.66/33.33] (This is critical to set, so that you lock down the Frequency)
CPU VCore Voltage. . . . . . . . . . . . [1.6]

Performance Mode. . . . . . . . . . . . .[Auto] (to start with I'd leave this to Auto and once you determine that your stable, then change it to see if it works for you.)
Keep in mind this is just a baseline to start with. Once you know you can boot up and all is well, run Memtest-86 to see how the RAM is doing, then tighten timings and Enable Performance Mode as well as Performance Acceleration Mode (one at a time of course), then run MemTest-86 again. The idea is to keep it stable but at the same time allow yourself as much performance at the stock settings for both the RAM and the cpu since you want to run at stock configuration. You can bump up the 'CPU External Frequency (Mhz)' as well or start out at the desired 216 or start with 200 just so you can make sure that it's not going to be to much and then bump it up. You'll want to slowly raise the FSB (bump it up 5 at a time) before you start tightening your timings on the memory, you'll find it's the best way to get as much out of your machine as possible and also determine it's limits in an orderly fashion.
If this doesn't do the trick then you probably either have really bad sticks of RAM or a bad cpu and should consider RMA stuff. Make sure you have an adequate PSU as well. It's at the heart of the system just as blood is to the body.
Oh and one more thing, Make absolutely sure you have USB Legacy Support disabled in the bios! It's a MemTest-86 and Windows Memory Diagnostic Killer, especially for WMD! In fact I would recommend that anyone who is wanting to test their RAM, disable this feature. Save yourself the false reports and errors by doing so. YOU'VE BEEN WARNED! 😛
BTW, here is an article on those sticks of Mushkin PC3500 Level II RAM
If you're getting 3.4ghz from a 2.4, don't complain that's great. Not sure what you mean by "RMA the OCZ for the P4P". If you RMA your memory, you won't have it on the P4P....at least not until you get it back. The OCZ might happen to work better on the P4P, but just a guess would be that since it won't handle 2.85v, it's probably "lax" in other areas as well. May be a bad kit. I'd tell them about the 2.85v problem, and add something like it won't O'clock past default DDR speeds. Ask them if it's possible if they could hand pick a nice set for you. Michael did, and they did for him. Geil did it for me. And yes to the Miller, but I prefer MGD. :beer: 😛Now the question is do I keep the costa and rma the ocz for the p4p?
RMA the china, hope for a malay, and get 4000 gold for the p4c?
Or just have another miller lite and be happy with what I got

OK. It's official. Xeon is a GOD.
Well, so far anyway. 🙂
I started with your default recommendations and ran memtest. 2 full passes with 0 errors. I had been getting about 7 errors previously.
So far it's running just fine and I will put it through the paces and see how it does.
After that, it's on to making this 2.6 a 4.0 ghz.....now where did I put those jumper cables....
Thanks again,

Well, then, the M0 may be worth picking up even if it is a Costa one.

You should know that there is never a for sure good OC chip no matter what the sSpec or stepping. You can only hope the the luck of the draw is in your favor and try to improve the odds with some specs from others that may have had luck with a particular batch. In the case of the MO stepping chips they are from EE chips that have the L3 cache disabled.
