I can't wait to get one of these under my Prommy :).
If your VIA chipset is a bad VIA chipset then it won't have AGP/PCI lock no matter what BIOS. BIOS 1005.020 should have had an APG/PCI lock, no?Quote:

I had only 2 hours to play with it and didn't have that particular BIOS available. With the 1005.020 the board wouldn't POST if AGP/PCI lock was activated. It works on that BIOS?
The board also maxed at 230FSB for SPi 1M (w/ Vcore, Vddr mods and extra RAM cooling) - and that was w/ both OCZ 3700EB and KHX3500 (BH5)
Looks like you got a good clockin' CPU there too - excellent :D
Lets see some 3D/SuperPi powah?
Yep, word has it that the early Via Pros where bad, a problem with locks. I guess the latest ones are suppose to work.Quote:

All the early Abit KV8 Pro boards failed when changing to locked AGP/PCI, as did MSI and so it seems Asus. Later Abit boards did not and apparently there are extra resistors behind the VIA chip.
What's this 5:3 ratio Charlie, do you mean 5:4 ? I found through testing with the Abit that to get 5:4 to equal 1:1 I needed an extra 50Mhz on FSB/Hypertransport speed . Testing was with pifast, I did not bother with 3dmark.
This was with a 754 board though with it's lack of memory bandwidth due to being single channel, 939 might have bandwidth to spare so not as badly affected by 5:4 and the high FSB then shines ???
I love AMD chips, I hate AMD chisets :D

hey guys....
rig runs nice when cold in the AM....68F in benching room, turned off for 10 hours.....ran this sPi first at 296 and then got 1/2 way through a sPi at 300........
this leads me to believe that there may be merit in sinking mosfets, cooling NB and using more fans on the bench :D
BTW, don't ask me WHY, but I've been back on WinXP for the last day, and the rig runs better AND faster than on Win2K3SVR.
Andy,
It's a quirky thing with the chipset, at 12x it is exactly 5:3, but as you change multi's the divider changes... but I actially LIKE this chipset, to me it ACTUALLY feels like a Canterwood...
Extremely nice board i must say. If the CPU´s weren´t so expensive i´d get a s939 rig right away.
So there is another ratio !
333Mhz to 400Mhz is 5:6 but when I set this I actually get 4:5 , because it takes it off the hypertransport speed and does a dvision on that ie /10, /12 etc etc.
Now you say 5:3 as well. I fear for my Windows Calculator .....
Regards
Andy
nice stuff charlie.
BTW where are you guys wiht the locks getting your boards from? zipzoomfly,newegg, gameve??
thanks
lol.........
Yeah, at 200mHz fsb, it's 160mHz mem speed, at 300, it's what? like 244-245?
OC Kid,
I got mine from zipzoomfly.com.... they take longer to ship than newegg, but it got here ok. But newegg is my fave...if I order by noon, I'll have the order the NEXT DAY!
EDIT: For those laughing at might Xabre 200..... I called Best Buy near here and they actually have stock on X800Pro (the only BB in LA area stocking it)........I may take the drive today :D
C
Ahhh I get it, and 1:1 200 HTT is 200 FSB?
:) you know you want to take the drive and pick up some more C02 on the way back :)Quote:

sporting some nice mem b/w
and I'm just a "joe six pack" overclocker..... just wait til Macci and OPP get their hands on it! What? 330 benchable? 10 x 330?
The RAM divider or HTT speed doesn't really mean a thing - its all about the RAM speed and timings. 360HTT 280RAM is just as fast as 280FSB 280RAM as long as the CPU speed and timings are equal. This is how it goes on NF150 chipset and I dont see how it would be any different on VIA - the is the part where the RAM controller is anyways..
5:3, 5:6, '166 mode' etc are basically the same thing. All mean that if you boot at 200HTT the RAM will be running at around 166MHz (depending on CPU multiplier).
CPU speed / (CPU multiplier + 2) = RAM speed w/ '5:3, 5:6, 166mode'
Tell me something guys, are the CPU ondie memory controllers still as sensitive to high vdimms? I can't afford to kill any CPUs :p:
thanks for cleaing it up
lookin good:D
It's not really an issue with the A8V, because you can't get it over 3.15v anyways... most of the guys "cooking" A64 earlier this year were all at like 3.4v+ on AN50R'sQuote:

Due to the on-die memory controller, you gain around 150-200MB/s memory bandwidth per 200MHz CPU frequency. :thumbsup:
11.5 x 305
I think that the problem was the Shuttle board or sumthing and not just the high Vdimm.Quote:

I've killed only one and it happend on AOpen board where my Vbt VR made a 'small' jump - Vbt went from 1.6 to 3.3V => instant CPU death :D
The Gigabyte boards (K8N, K8N Pro, K8NNXP, K8NS Pro) I've used haven't killed a single CPU and I've had Vdimm up to 3.87V. its normally 3.66V - 3.7V for benching.
"small"? lol :D
first of all great stuff...
if i had a money id buy one of these socket 939 FX's
slight off topic question(s)...
1. are the socket 940 and socket 939 FX's similar in performance? i understand that the 940's have to use ECC mem while the 939 does not... how much difference does it really make?
2. both the clawhammer/newcastle(A64) and sledgehammer (A64-FX) work on all the 939 socket boards, correct?
great OCing charlie
whats the issue with the SPD chip on the KHX3000?
and whats the issue with the vDimm circuit on the A8V?
well here's the deal: KHX3000 sticks have an SPD programming of KIngston Technologies PC2700 256mBQuote:

Now the Asus motherboard looks at that and says: Ahhhhh.....slow DDR, so it defaults it to the 5:3 divider (DDR333) There's no way in BIOS to reset it....
The Vddr mod... it works fine up to about 3.15v where it simply locks up in Windows, why? I don't know.

hmm, so far, shipping bios, 1003.006, currently at 240Mhz 3dstable, no vddr mod so had ot drop to 5:3 after 220Mhz, 2x512MB of bh-5 cas 2,2,2,5,7,16 . At 240 , assuming no lock and assuming a 1/6 divider, that would be 40Mhz, ain't done any real testing with this x800 pro but what kinda AGP frequency's are they working on?
Also my kv8 pro abit board with stock shipping bios(brought the day they hit uk and musta been almost a month ago, i'd say one of the earliest) did 250Mhz 1:1 2x256mb cas 2,2,2,5 no mods and would also run most dividers at 280Mhz HTT with mem around 200Mhz fine so i assume that lock is working too.
Some info on this board, i got this from various sources, not my bios contact.
Aparantly sales have taken place in europe(UK and Germany) but there shouldn't be any boards available in the US. There is a lock issue but not all boards are effected..so you may get lucky.
Im waiting to see if there will be a new bios out soon..don't mail me for it, as soon as i have it you will i promise.
Charlie. I think you need to start a data base and compile a list of boards that have the lock that works and ones that don't.
We also need hi res pics of boards to find where the 2 resistors are missing that enable the lock.
Macci 1005.020 is a PCI lock bios, your board must be an early one with the resistors missing, once we find where the missing components are and what value you should be able to mod it to lock.
