Isnt the fx55 more than this? Screenshot

[Malmedahl]

I Have
FX-55 SH7-CG
A8N-SLI DLX
OCZ Platinum rev.2,2*512
OCZ 600w
Its all watered but it seems that i cant go any further than this, having it Prime stable.
I cant do it without the vcore though, so is it perhaps the mem-controller that is the bottlenck of this.

Cpu is 33 Idle/40Load


Im not that familiar with the ID:s of the FX55, can anybody tell ?

[cantankerous]

that prime looks odd. you should have alot more tests than that in 9.5+ hours.

[Malmedahl]

Yes,i know. I Tried to reinstall it but it keeps doing the same. Dont know why

[Torin]

Try going for a higher FSB.

[saaya]

lol, rather a lower fsb, could be that your cpu is already close to the max and thats why its running that slow... but id be surprised if 2.8 is already the max...

your temps are totally wrong though,no way your load temps are 40°C at 2,8ghz with 1.68v ;)

maybe the cpu is running too hot and its downclocking itself? hmmm
make sure you have cnq disabled... :shrug:

does it run ok at stock speeds?

The temps is probably right, its on water

You know that the asus a8n sli is not stable with ram at 1T over about 240/245mhz, espcially not tccd stuff. It could be something related to that limiting things. maby your board is maxing out a little lower than most? (just a thought)

[SuperDude]

maybe too much voltage? or not enough to the vdimm

Well i could probably play around to find it stable at 234 HTT but i know that a8n-sli DLX isnt that pleased to have TCCD chips installed.

Though i think that the FX-55 would perform more than 2.8GHZ with loadtemps under 40 degrees celsius.

I found at the german asus ftp the 1004-001 bios version. havent tried it out yet though, perhaps sometime tomorrow.

I beg to god that it is an BIOS related issue.
:confused:

[DoGMaN]

My A8N-SLI maxed out at that exact same HTT speed, regardless of multiplier. I took it back today.

[HARDCORECLOCKER]

:D I don't know much about that board, but at 2,8 on water Ya FX is still "sleeping" so go for another board or try to find a BIOS MOD for the A8N -
sometimes a good BIOS changes everything..........

If nothing helps, go to Ya FX dealer and do this: :slapass:

:toast:

[bias_hjorth]

Say is the PCI locks activated? There´s no way the memory controller could max out already - I def. thinks its a board issue.

[jjcom]

why don't you try something like 200x14 and then something like 210x14 etc rule out memory issues and high HTT issues with the board

that may be your prob. i have heard quite a bit of complaining about the A8N-SLI

[Kanavit]

here's is my A64 3500+ newcastle for comparison sake. possibly very bad mem controller too can't do more than 235mhz @ 1t.

which bios you folks using ?

[Malmedahl]

Well, this is the A8N-SLI DLX we are dealing with here.

Im going to try some 200*14 to see what the cpu is up for actually


ÉDIT:...Hm... very strange when i apply 200*14 from Clockgen it automaticly reboots. As if i had a multiplier lock, ehm S :rolleyes:

It also reboots at 186*14 wich is the stock speed in Ghz, seems like i have got my self a multilocked FX :rocker:

I have 2.9 vDIMM
1.65 vCore
pci-e 101mhz
pci @ 33.34
I have everything i dont use turned off in BIOS 1003-Final.

[reject]

eva has the sli board
you cpu acts likie a pre relaease fx-55 on air
reseated waterblock?
definately get that latest bios if you havent already, it improves oc on that board a lot
Oh yours vdimm mush too high for TCCD drop it to 2.6-2.7v

[jinu117]

A8N SLI still is buggy in my view. My FX-55 on water is priming right now @ 2.94ghz. (no idea on load temp as MSI sucks on that... reporting 61c lmao.... water temp is around 29c and thats with actual 1.73-1.76v)
This chip did prime 95 on mach II for 3.25ghz though.
Tips fo A8N SLI. When flashing bios, use the asus windows update stuff.
Make sure your LDT locks. (check ntune or CBID)
TCCD and VX doesn't do too well with this board, if you have spare BH-5 stick to it.

Tried once again and seems like it just didnt wanna change the multi from windows unless i had the HTT very low first.
Then i managed to climb to the exact speed as you did. 2.94Ghz. Reaching 40 degrees load
Havent Primed it yet though, but it was Super Pi stable/1M several times.

At least the CPU seems to work as it should. A couple of BH-5:s is exactly was is needed here i think. Would they still perform better with 2*512 than these TCCD?

210*14
1.65vCore
3*LDT
2.9vDimm <-- Perhaps lower it as Reject says.
2.5-3-3-10 1:1 1T

:confused: Ähm, You'd alwayas try to change the multi in Windows?

Never heard of that this will work - change it in BIOS.........

It have always worked fine LOWERING the multi from the original 13, back & forth. Uppering it was a little more tricky.

As long as it works...

Heres with gigabyte K8NXP SLI. This board wont go past 290 with 1:1 mem. With divider at 166 scaled to 306. FX is week42GPMW

[Malmedahl]

Nice OC mate!
What memory is that? If it is TCCD.....hm,never mind, it is a whole different MB.

You know any differencies between our FX:s, other than mine are 5 weeks newer??
I have: 47DPMW
you: 42GPMW



Seems like i have 3 options. Descending in price =)

#Buy 2*512 BH5
#Buy a different SLI motherboard
#Wait and hope for (probably nothing) a GOOD working BIOS

very curious about the BH5 :)


As to tell by the shortcut to fedex, i guess you are as unpatient as i am ;)

Would the FX do 3Ghz on water or that is a bit too much. I'm running 250*11, 2.5-3-3-7 1:1 1T on air. Upgrading to water soon and hoping it would go much higher. Mine wont go after 250 no matter what multiplier I use at the moment.
