New World Record of CPU Frequency at 8805.64MHz ! it not my stuff but.... from our forums member named " ksin " he braking new world record of CPU frequency by AMD Bulldozer FX-8150 at 8805.64MHz and only using LN2, this clock are crazy it close to 9GHz and you can looking more details and some results (SuperPi@8.5GHz)from him by here >> http://www.overclockzone.com/forums/showthread.php/1533313-lt-lt/page62

multiplier 29 is damn low :p
CPU maxed out ?
let's see if Andre has a backup :D
Is this really legit? It's a BIG jump, using just LN2 and low voltage.....

15s superpi @ 8.3 Ghz ?
15s superpi for bulldozer it's 5.6-5.7 GHz or so
multiplier 29 is damn low :p
CPU maxed out ?
Not sure because I did not stay there with him today. But yesterday we are just disappointed with the Ivy Bridge together.

Yah very big jump but maybe new lot of FX can do like this because this chip just bought yesterday and unbox(Maybe can :D) today.... boom ! WR
Do you have any batch and wafer info? :)
I'll ask to him take photo for you maybe tomorrow i will can get that ;)
Christian Ney
05-27-2012, 23:17
got a new batch too, very recent, I may test it then :D
I'll ask to him take photo for you maybe tomorrow i will can get that ;)
Thanks bro :)
holy crap that is a high frequency, nice to know people are still playing bulldozer
Edit: any reason the picture has to be so slow lol.

Possibly bugged? Spi time is really slow and htt + ram kinda high for validation.
If that's right it's time to dress troufman up as Goku and go for 9ghz :D

Yep, pi at that frequency is super slow. Could that frequency be replicated with lower HTref and higher multi or at least get close to it?
Voltage seems low as well, but everything is possible.
Pi result might be bad if other cores are clocked much lower and no affinity is set?
he probably didnt select the core that was running at that frequency hence why Pi is "slow"
btw is this submission blocked? I don't understand )
Thanks bro :)
Your welcome bro ;) and about pcb code he will give me later.

Yah.. why it blocked i need to know about reason and why cpuid rejected too ?
btw. for hwbot block i understand because following cpuz validation that the rule ;)

cpuid/cpuz rejected the validation because cpu was throttling so 8.8 GHz wasn't the real frequency that's why the superpi score was so low/slow
cpuid/cpuz rejected the validation because cpu was throttling so 8.8 GHz wasn't the real frequency that's why the superpi score was so low/slow
Ahh i see, so that mean some bug from system right for showing it to 8.8GHz ?
Thanks for answer :)
______________________________
Last update... he just try again to night and i don't know it is still throttling again or not but he can get a little bit more MHz to 8855.2MHz now !

btw. waiting for cpuid checking ;)

Yes to be simple 8.8 GHz was kind of target speed but cpu was throttling at 5.607 GHz
I kinda wondered..... but the feeling of 8.8GHz was nice while it lasted.
9062MHz "that easy" at <1.90v. Sorry, it's getting a little bit silly now.

but cpuz validates it... amd to be blamed? or is this another tesellation tweak? lol
if it is a bug with mobo/cpu/whatever why appeared now?
noone had this problem before?

CPU-Z doesn't always tell the real voltage...
Yah.. latest he can broken 9GHz ! it will damm nice if it real but waiting for CPUID again :)

Hope it could be legit after all :w&s:

It takes 24 hours to cpuid (valid.canardpc) to check if submission gets rejected or validated.
I.nfraR.ed
05-28-2012, 19:58
It's not instant validation anymore or had never been?
Christian Ney
05-28-2012, 20:02
There are several checks, first is instant then there is another one every 24 hours that dooesn't check the same stuff as the first one
I really hope, this will be WR for validation...9 GHz is nice wall :).
http://www.youtube.com/watch?feature=player_embedded&v=YqRQydLz6qU
I thought CPU-Z was updated because of how AMD chips behave?
About the video: if it's stable enough to pause and film, it ain't on the edge/ it's in no danger of crashing. If I was at 9GHz, I sure as hell wouldn't be so chilled out
Or.... the BS answer: the psychology is wrong. Break the CPU MHz WR by 500MHz and just react with "yea, whatever. I'll stop and film it" LOL really?

Hmm OS is looking very stable for such a high clock. Unbelieveble

Hm, noticed from a picture he's running the latest bios 1402, which was released to public 3 days ago.
Could it be this bios is bugged? The difference with the previous record is so big and he's still going up. 10GHz soon, anyone?
Windows 7 gadgets are happily running, while he's validating.
Yeah, I know I sound like hater, but I still can't believe it.
Wonder if he's increasing the HTref/multi in windows or directly boots with the dialed settings and doesn't touch anything while in windows. Voltage reported by cpuz is still 1.89V.

Well noticed mate ;) It's clearly bugged validation... so sad :(
Edit: any reaction on this side should sounds like hater's statements... but here nobody can be seen as a hater. We all doubt.

Will give a try with my chip + CVF

Excuse Chris Dino :D we're so accustomed to see you joking...
But I recognise that he's right, we don't need no other board or bios to be convinced. Just want some efficient run at max of that chip.
Some numbers cain't be wrong!!!
(PI!)
Isn't it a common problem that AMD efficiency bombs at high HT? Example@ Sempron wPrime runs are at 6.4GHz..... PCMark05 runs are at ~4.5GHz. Of course....there are still guys running massive MHz, so there is still an efficiency comparison
If anything, I actually agree with Dino - an attempt on another motherboard shall be made.
This is not the first case when I see Crosshair V Formula boards produce results that are not in line with reality (reality = results done on other boards). As some people probably know, me and websmile (a guy from Germany) are between the most active DDR3 binners in Europe. We have a very clear idea where the tRCD walls and MHz/volt scaling limits are for most ICs. None of us has a C5F, but the C5F results we see from fellow binners (sometimes with our ex-kits) usually greatly exceed what we thought was the max of specific kit or IC. So, for this matter, I, personally, would not recommend relying on memory overclock results made on C5F when looking for pre-binned memory (unless you're going to run a C5F as well).
I could be wrong and the board is an engineering masterpiece so, don't take me 100% seriously.

The several irregularities Sam mentions are true, I fully agree on that. The Crosshair 5 may be an excellent board, but it sometimes produces results that are too good to be true, and which are not reproducable. This result was widely discussed in germany as well, and efficiciency on 1M etc make it very likely this is bugged, which is disappointing, but these things happen in world of high oc
i think its clearly that he isnt capable of hitting 9.1ghz, not even close to this, lol :)
new batch, good position at waffer, luck, this all aspects can be possible...We need Andre Yangs old good one chip. His FX hit "easily" over 8500 MHz, I believe for answer from him :)

There is simply no comparison between the 2 chips. One hits 8.55Ghz, another 9.1Ghz. Difference of 600Mhz. And if you see the video, that will redefine the word 'easy' for overclockers.
we will see for next proof, maybe he will try again in superpi, if superpi run will be about 10-10.5s at 8500 MHz, I have no problem believe 9 GHz validation.
Between FX are very big diferences, at air some can hit only 4500-4550 MHz stable, but there are few over 5000 MHz stable. The same with LN2, worst of these hit only 7000-7200 MHz, the best over 8500 MHz.

How many over 8500 Mhz FX chips have you seen????

What new batch? It's (1204PGT) older than my second 8150 (1209 PGN) that I got from RMA and it's total crap on water. However not tested on LN2 yet and yes I know you can't make conclusions over different samples. But 600MHz over the previous record isn't something to believe easily, plus all his big validations are rejected.
Someone should test this 1402 bios, I don't have the board. Refused to buy 9xx chipset board from Asus when the Crosshair IV didn't get full-working bios.
i ll do it tonight, atl east on air/water and @ weekend on ln2 with my good chip to see if it can pull some 9ghz runs, lo lo lo
I have no problem believe 9 GHz validation.
:D
Really?! No problem whatsoever to believe it? I can give you at least 5 reasons why you should be slightly suspicious :p

You should easily get to 6 - 6.5GHz range on air, I believe :P
I can even give you my new batch FX - 10GHz candidate chip with 1.79V.
the banik: the main problem is, no much people testing FX under LN2, this is real problem. If u seen Chews* FXs, most of these scaling good over 8 GHz in quick test. And it was not binned chip, after this he took one for LHe with "lucky" hand.
Example from my experience: I have 4 FX chip home. And there are differences. One is good for AIR with very good power consumption. But poor with LN2 (7300 MHz max). Second is 7700-7800 MHz chip. Died under LN2, at air was not special, average chip. Others two are 8150. One is average at AIR with "good" power consumption. Second is great AIR chip, but very hot and hungry. This chips still waiting for LN2, my estimate is second chip will be 8 GHz chip with LN2.
If I got support as some guys here, I can testing more FX chips with LN2. Ln2 is cheap here and is about 5km from my home :)
:D

Did u read all my text?:) If he show good run superpi at 8500 MHz, after is at least 8800 MHz validation possible. 8500 MHz superpi must be at least 10-10.5s (without much tweaking uncore, operating systems and bad skill). Tuned FX at 8 GHz has superpi1M about 10.6s
It's quite optimistic to think that because you have 4 chips of varying quality, the silicon has another GHz in it....
