This seems like something weird that I haven't found a valid explanation for.
Note - This isn't my cpu
http://valid.x86-secret.com/cache/10591.png
Motherboard used is a Gigabyte K8NSC-939
doesn't use the nf3 ultra but nf3 250gb chipset apparently
Maybe something to do with it defaulting to 11.5?

Wow, that is interesting. Well there are two possibilities:
1) I don't know the explanation, but it is that way some how
2) You found a security bug in CPU Z.
gigabyte boards are know to cycle via cpu codes freq. I think Its jsut a bug is all :)
check out some of the top 3dmarkers with gigbayte boards you will see a 2600mhz cpu showing when they where really running a 3300mhz cpu, lol
it's defaulting to 11.5? did whoever has it try clearing the bios? :stick:
edit: wait. i just realized... i'm slow. haha, a 3200+ can't use an 11.5x multi :slap:
It's weird but apparently the multi is locked on his boardQuote:

I want a decent OC'iong mobo that will do that :P
(give extra multis)

well if we can figure out how amd locks their cpu's.. we can figure out why it's doing this. was it ever established that there's a small rom in the core that stores the needed information for the bios?
hehehe weird indeed...somebody send me there spare 3500 to test in this mobo, maybe it will have a 13 multi. :toast:
rofl
@ArcTan can u pls try the limit of the CPU @11.5 & @10 mutli 2 c if it stop @the same clocks
totally weird but i feel i'm lucky if that clock is real and those proc are mine.
11.5 multi on 3200+ can the proc be OC then?
nice mate nice ;) - Eventhough I perfer high FSB ;)
But... If mem is the bottleneck in a OC, that CPU ROCKS :D
Best regards

Weird, weird indeed.
I put my money on CPU-Z bug in relation to Gigabyte motherboard.
get your mate (or whoever owns that board) to run CPUID and any other freq. identifying stuff, see what speed they say it is. Also do some benches (e.g. sandra) to see what speeds it gets, if it's the same as a 2.3ghz Athlon64. If it is, lucky bugger.
does it saythe same speeds in the bios? or does the bios clock say different?
Yep this is very weird.
Ok fellas...this is my chip, and from what i can gather it is in fact running at 2.3Ghz. A short story...I had this chip running on a AV8 for a few weeks playing around with some Gold VX4000 and 2x512 Bh5(KHX) combined with a booster and it was your standard 05/05 3200 with a 10x multi. One morning I slotted the BH5s in without resetting the cmos and from the time I started the PC I had no vga signal, refitted VX and still no vga. Ordered K8ns-939 and got a K8NSC-939..so I slotted the cpu in with the VX and loaded windows and stuff and was thinking this is pretty quick (a lot snappier than the AV8) installed cpuz and found the multi at 11.5.
Im not sure if the cpu is in fact unlocked or the chipset is to blame. Ive run loads of mem and cpu benchs.
The old SiSoft reports
Mem Bandwidth
11.5x200 3647/3711
11x5x226 (2.6Ghz) 4244/4257
Cpu Arith
11.5x200 6256/4656
11.5x226 6808/5193
note this is on SSoft Sandra 2002

At 11.5x 226-2.6Ghz I get a 32 sec Pi . I guess im going to have to wait to RMA AV8 to find out if cpu or mobo is to blame.. :stick:
Ive tried almost all programs to try and adjust the multiplier, there is very limited adjustments on this budget mobo, no divider and no multi. There is only one bios for this mobo. Its been sugested the A64 instructions are missing..not sure/dont care..also it runs out of sync due to half multi..RAM only at 192 for a HTT of 200.
How much? :slap:Quote:

lol I can imagine a shed full of crims making counterfiet cpus :slap:Quote:

You may have hit on a rosetta-stone of A64 unlocking. you'd wanna analyze what bridge or code difference there is between x10 and x11.5. Is it like ONE bit difference in the code? Suggesting one bit of a default bridge got zapped and opened? to change the code to 11.5 instead of 10.
Ive been wondering how come noone has figured out how to UNLOCK these friggin chips yet.
Im suspecting its a bridge setup but under the IHS and under the soldermask on the substrate. If we knew WHERE it was, we'd all be digging in with exacto knives ;-)
Assume they speed sort the chips BEFORE the IHS goes on. make the tweak to the lock, and slap an IHS on. Then SHIP IT.
That sounds much along the lines ive been thinking. I wish I had another 3200 or 3500 to test on this mobo then id know either way. I wonder should I take the IHS off and have a gander...is there any pics of a A64 without IHS on the web?
I bet testing another mobo and CPU would be more intersting...Quote:

I'm just gonna be a skeptic and say it's a bug. Strange though. I've seen MSI's corecenter playing funny buggers with what my CPU frequency my 3200+ is being reported as, as well as ThrottleWatch on my P4 when minimised fluctuates randomly when showing the CPU frequency.
I think i'll just put it down to being a bug.

Yeah ive tried Crystal cpuidQuote:

Very strange, just like a totally locked CPU...
Guess that Cool n' Quiet doesn't work either? (not supported according to that pic)
I havent seen any reference to cool n quiet in the bios. I guess there are a few things that are not supported. Has any1 else got a winchester on the k8NSC-939? (long shot).

Crankybugga:Many motherboards have CnQ enabled by default, but no sign of it in BIOS or any chance to disable it. That doesn't matter though, because it won't start until you install driver and set the Power management to Min(?), so if you don't want it, it won't kick in. I think I've seen somewhere about a Gigabyte mobo with no BIOS option, maybe it's common in their budget boards. So maybe it works anyway on your mobo, but possibly not with your crazy CPU....
Edit: Your mobo is not listed here, but as you can see there are some of them that haven't got a BIOS switch (most of them S754 though).
den, it sounds like cool and quiet is on with ur a64? cuz wut i hear is that when ur cpu is idle, cool and quiet will under clock it so that it gets cooler, and if u have smartfan on, teh fan will run quieter :) hince the name, so thats prolly y u might see the change in cpu frequency on ur 3200 i dunno bout p4 thoQuote:

Doh..just found the above m/b is s754 :stick:
Well just install AMD drivers and check it out, that's the easiest way.
Even an expensive Gigabyta SLI board lacks a switch for instance as you can see in the list, so you never know until you tried...
Would "CnQ" get highligted in CPUZ only if installed?
Have you tried AMD CPU info or CPUID?
And?
I tried another gigabyte bios for the NF3 ultra to attempt to gain multi settings in the bios but to no avail. I really need some1 with skill like tictac to have a play with the orig bios and enable some things...if they are there...
Did you try Ctrl+F1 already?
Surely did. :horse:
bump
any new about this curious cpu??
nah still giving me 11.5 multi and performance to match. :woot:
If its a bug.... a bug that can alter the multiplier UP on a A64.... then its a bug we might all want to catch ;-)
Would really luv to know what going on here. Hard to belive AMD shipped a mislabeled chip....and none default to max XX.5 anyway.
I still stick to my hypothesis that a single "bit" got zapped somehow in the locked multiplier bridges that we dont know how to access, and the result is the odd unplanned multiplier you have.
Definately makes sense...It was limited to 10x multi in AV8...some RAM probs killed the AV8 and some BH5, I ordered a cheap intermittent m/b and from 1st boot the cpu was at 11.5Quote:

i thought the nf3 250gb was a 754 chipset ONLY?
Its 939 also.
How the hell does an Athlon64 not support it's own instruction set?
I say the chip fried a few brain cells or is counterfeit.
gimme the bios link
can you make a backup of your bios file?
There has only been 1 bios version for this m/b...F1. I have actually flashed the bios to a d/l ed F1 bios off the gigabyte web page. The bios does not allow for multi adjustment at all, which is a real killer.
The bios link
There is multiplier adjustment
Hammer FID Control
under :
Mobo Intelegent Tweaker (MIT) :fact:
Not on this setup...I know there should be...but there is no access to FID.
Here is a bit more info.

omg i want some bh5 fries my cpu like that but 2 multi more plz xD
how goes hte progress, i still say counter fit, but tha's me....sry for the disbelief that amd would be that dumb lol
Sounds like he has a friend that can burn fuses and is just screwing with everyone. =P
lmao that would be funny quan lmao
A lot of these boards seem to have issues with CnQ and more than one memory stick..perhaps somehow distantly related.
