XFX 790i - FIRST LOOK

[Tatty_Two]

Mines in! Finally got the quad but volts are low....temps are high, maybe needs re-seating. Will update you in a bit.

how high do you mean?

 

[DOM]

I think the Q's are just hot, IM at stock at 1.064v F@H SMP hottest core in speedfan 4.34 beta 51 is 52c and everest 57c its the same in core temp, everest and core temp

 

[Tatty_Two]

how high do you mean?

Idles at 36C on all 4 cores at stock....way to high, especially as stock votages are only 1.15V!! I have had two Q's before and they dont get near these temps with a TRUE and with dual fan setup, I will re seat and re apply paste tonite, if it still stays that high the chips going back!

 

[Tatty_Two]

Tatty_One can you use Ntune for your motherboard?

It won't let me change any settings on my board.

Forgot to mention D.....yes I can use NTune, it's all there and actually very nice! I got a Bete edition on the driver CD with the board.

Well if a true cannot cool it then I don't know what can.

true... these temps are on the warm side with tendency to become hot on full load...Let us know after reseating...good luck, man

you must be in luck...it just doesn´t work for everyone...

It may be that the XFX is NVidia reference and the Anus isnt. Bare in mind, those idle temps are at 2.4gig stock, if I raise her to just 3gig the BIOS will auto raise the voltage needed and it works! trouble is the idle temps then shoot up to 42C!!!!

Hmmmm I wonder where I can download this beta.

Seeing as I know you, have just found the latest March 2008 version supporting the 790i

[Tatty_Two]

Does it work for you D?

 

[Tatty_Two]

Right, the quad is going back to malaysia I upped it to 3gig on just 1.2V which sounds nice but the fookin idle temps were 46C!!! Now I have re-sat that damn CPU and cooler 4 times and I have had enough.

My contact is going to send me a Q9450 at no extra cost for my trouble so I will give that a go but by the time this one is returned and that one gets here it's going to be almost 3 weeks so I have bought myself a cheap E8200 that I am going to overclock the hell out of until the Q9450 arrives and then fleabay the E8200.............I should have just gone for the Yorkfield in the first place :shadedshu even though the Q9450 only has an 8 multi, this board supposidly can hit FSB's of 520mhz with a Yorkfield so 4.16gig will do me!

The 8200 will be a nice litle overclocking project for me, early results from the 790i Ultra show possibilities of near 600mhz FSB's with duellies.......now that sounds nice!

 

[tzitzibp]

Shame....

btw what north and southbridge temps did you get while cpu temp was 46C ?

NB 32C.....SB 29C I think it was but that was with pretty high ambients, not even warm to the touch though under all that heatpipe cooling

these are really good...... shame about the cpu...

 

[Tatty_Two]

yeah but the real test will be when I take that FSB to 550+mhz with the E8200, with all the voltages she will need it will be interesting to see how the cooling handles it, especially on the NB/SB.

agree. at least you have a good starting point.
better than I have seen in a nvidia mobo for a while...

Some helpful info for OC the 790i from
http://www.xtremesystems.org/forums/showpost.php?p=2924728&postcount=4

first of all you have to run RAM in black slots

in terms of volts please leave all on Auto except for Vcore and vdimm. I assume you are trying to do 450*9 = 4050

so set your vcore to whatever your CPU is stable at those speeds (probably around 1.35v for most quads) >> you can always bump up or down depending on how good your CPU and coolin is

i also suggest slowly starting from 400*9 in bios and them moving in 10MHz increments to 450 to see where you get stuck

Also, are you sure your CPU can manage 450MHz FSB????


[EDIT]


Quote:
CPU Multiplier 8x (ah ok 3.6GHz is the goal fair enough)
PCIe _1 and _2 MHz Auto
PCIe _3 MHz Auto
SPP <-> MCP Ref Clock Auto
nForce SPP -> nForce MCP 4x
nForce SPP <- nForce MCP 4x

CPU Spread Spectrum Center
HT Spread Spectrum Auto
PCIe Spread Spectrum (SPP) Disabled
PCIe Spread Spectrum (MCP) Auto
SATA Spread Spectrum Down
^^^^^ DISABLE ALL^^^^


FSP Memory Clock Mode Auto(1600)
Also unlink memory and run it at 1600
Memory Timings Optimal
tCL Auto(7 > also try 8)
tRCD Auto(7)
tRP Auto(7)
tRAS Auto(20)
CMD Auto(1T also try 2T)

tFAW Auto(LEAVE AUTO)

Limit CPUID MaxVal Disabled
Intel Speedstep Disabled
CPU Thermal Control Disabled
C1E Enhanced Halt State Enabled
Execute Disabled Bit Enabled
Virtualization Technology Enabled
i usually disable all for initial testing
and then enable 2nd, 3rd and 4th for 24/7 system

CPU Core Auto(1.17V ok if your CPU is stable at that >>> for FSB OCs i had to increase CPU voltage to reach ultrahigh dual core FSB....for quad cores 450 is pretty high)
CPU FSB Auto(AUTO)
Memory Auto(1.9V-2v <<< this undervolts on my board by 0.05v so keep that in mind)
nForce SPP Auto(AUTO)
nForce MCP Auto(AUTO)

GTLUREF Lanes 0-3 Auto
LEAVE GTL REF AT AUTO FIRST
and then later play with values on all four lanes slowly increase to positives first....one user found stability around 30 or 35 but it doesn't mean your setup will be the same

this is a kick in the sack

[Jikiri]

Hmmm guess i'll sit on my CC a little while longer maybe with any luck the e8600 will show its face by the time they get this sorted out

 

[DrPepper]

nice looking rig you got there tatty good luck with oc'ing it, its just a shame about the quad

Fortunatly, no data corruption for me, couldnt cope with that on top of the problems I have had with this Q6600 the E8200 interim solution has arrived, just gotta be patient for the Yorkfield to finally get here, sent the Q6600 back today.

Thing is, the 790i is the only solution on the market for low multipliers IMO, results so far show it can hit FSB's near to 600mhz without mods on a duellie, and 560fsb's with Yorkfileds, intel chipsets just cannot do that.

My M/F will hit 570 or so but my ram cannot keep up. I have seen MF/RF hit 600fsb. They can do that look on the extreme forum.

 

[tzitzibp]

any results with that E8200 ?
