It seems to me that since the AV8 says rev. 1.2, that maybe prior to rev 1.2 there were some issues.

I'm more inclined to believe Wesley Fink at Anandtech who has had direct contact with Asus on this matter. This was his comment about the Hothardware review of the A8V:Quote:

Below is a copy of my fault report and reply from ASUS.
Dear Lee,
Sorry but the A8V does not support unsynchronised mode because the VIA chipset is not stable under this mode, indeed we never claimed that it would do so, it isn't to do with resistors or a rework on the board. It will support other overclocking features of course. Could you tell us where you saw the resistors mentioned? We would like to know so we can quash this rumour.
"I am really shocked (the) reviewer barely mentioned the missing PCI/AGP lock on the Asus A8V Deluxe and the problems with the premier VIA K8T800 PRO feature - the addition of a PCI/AGP lock. I have had an Asus A8V for several weeks and I have been working closely with Asus to fix this problem. The board also has had serious stability issues with overclocking an FX53, which have been improved if not fixed with the latest hardware upgrade and BIOS revision.
I have been able to reach 265 FSB on the 2nd revision of the A8V with the latest BIOS that improves FX53 compatibility and OC problems. The nF3-250 Ultra closes the gap with VIA as you can see in my chipset launch review at AnandTech on June 2, and the AGP/PCI lock does work NOW on every nF3-250 board I have tested - Socket 754 or Socket 939. The same can not be said for VIA, although the situation is definitely improving.
The revised Asus adds 2 resistors that enable the PCI/AGP lock. My review will not go up until Asus has fixed the last remaining problem - a serious stability issue with just the FX53 CPU. The 3800+ has no such problems on the A8V. This is shaping into an excellent Socket 939 board, and Asus has made giant leaps in resolving the issues with the A8V Deluxe."
So again, what the hell is this "revised" asus. Is it rev 1.2 or what?
could it be 1.02? thats the revision of my board and the locks aparently work. 270htt with 1005.020, 240htt with the 1003:confused:
what is the highest stable fsb you get in 2-1 sync with the locks on.
between 242 and 250HTT. 242htt will 3dmark, 250 will not make it in windows.

that's pretty decent. Is that 2-3-2-5? or 2.5---
2-3-2-5. and i thought those were my worst sticks of bh-5 LOL they may have 245-247 in em but after 250 kicked me i was done for that day and put my gig of kingston back in
guys.......I have Clockgen for A8V, straight from Franck
pm me :D
Mongoose, 242 1:1 (or 2:1) is nice with your BH-5....is that with Vdimm mod?
C
no vdimm mod. but only 2x256 meg sticks xms3500c2pt 1.1. sent you a pm for clockgen also:D I think its some kind of perfect match or something memory to board. ive got 2x256 of xms3500c2 1.1 that did 231 at 3.04v on my nf7-s 2.0. these plat. 1.1 sticks wouldnt do 225. the c2 sticks wouldnt do 230 on my a8v even at 2.5-3-3-8 and these pt do 242 at 2-3-2-5. I have no idea whats going on with em.
also according to a poster on FM that contacted asus and a high volume retailer. serials 45MGOJxxx should work and 45MGOKxxxx and up will work.
And later corrected himself to ****OJ**** serials. mines a OJ board and the locks work so...Quote:
Only boards with seriel number 45mg0Kxxxx and upwards.
older boards DO NOT support agp locks. I have checked this with ASUS and a retailer who is in close disscusion with ASUS. anything below locks up at post. (These are just general rules) some below may work, not many.) something to do with the VIA chipset.
Just installed it. Works like a charm. Again, the AGP and PCI frequencies remain locked when I change HTT.Quote:

really nice of cpuid.com to get the new proggie out so fast! I like it a LOT more than setfsb....
Mongoose,
I only have doublesided 256mB BH-5... hope the A8v likes it...
Well, good news locks work, bad news is the vdimm mod doesn't. Haven't checked the threashold, but at 3.0v it will not boot.
Has anyone tried the A8V with 4 double sided dimms? I'm wondering if 2T is forced enabled, or if it still works at 1T. I'd like to be able to run 2gb of my XMS3500C2 BH-5, but not if it kills my memory performance.
My replacement FX-53 arrives tomorrow. I now suspect that my original was ok, but the 1005.020 bios wasn't available before I returned it, and stability was horrible. At the time I didn't know of the FX-53 issues with the A8V.
Is the board/system reliable with the buss locked? I ask this because I just received information from ASUS that it would not be, and that VIA has problems with this feature. They told me that if you use them it will not be 100% reliable. That is supported by the fact that the released BIOS does not support it which is why you need the beta to even attempt to use it.Quote:

Still, if it will get through a 3DMark run, that's all you need, right?;)
This sounds like the old Vtt problem with the IC7 series of boards.Quote:

Yeah, I understand that... but more importantly, can you boot at 2.8V and TURN UP the Vdimm to 3.3??Quote:

so this confirms my experience with the mod. I wonder what the problem is. I would have thought this would be the same as sk8v. It is the right point,but the board is acting like it has a vdim governor. I hope someone can figure a way around this.Quote:

interestingly enough, remember that Bigtoe said the next BIOS will offer higher Vdimm.....maybe the mod won't work because the circuit is already designed for highr voltage???? I dunno'

It still seems a bit quirky to me, at least with the FX53. I don't really get a real warm and fuzzy locked feeling. ;)Quote:

As far as Charlie's question about turn voltage up in windows, tunrning the voltage up and down like that is going to be risky at best and it seems to me the one time I was able to boot into windows with the mod on at low voltage, it was very unstable no matter what, so I think there is a issue period.
well I wish that they would hurry up and bring that on.Quote:

I don't want to make out like this board is one great big POS. I think it does have potential, and as it is there is pretty good performance. I think we are just impatient guinea pigs. :)
Well I'm really impressed with ASUS in general. The SK8V was beautiful. I still use one with an FX-51 for my gaming rig. I just wish I was hearing things like "the locks will be supported in the next BIOS release" instead of "VIA is having problems" or "we never stated that it would have working locks in our advertising", etc.Quote:

That's the main reason I cancelled my order. I may get an NF3 Pro 250 939 to play with, cause this s754 one is pretty cool.:D
For the time being..........
does anyone have OCZ 3700EB sticks?? cas2.5-2-2-11-16 may be nice at about 260mHz
