Lets see if we can eek 500FSB out my E7200

[Ket]

Straight to the point, I'm quite settled on 480x7.5, but I would like some more bandwidth :up: *Oliver impression* "please sirs, I'd like some more bandwidth" :D

So far 480 seems to be the max stable I can get. As some of you know, I switch between various boards quite frequently so heres the current setup;

E7200 @ 3.6GHz 480x7.5 (of course)
TPower I45 + mBIOS
Cellshock PC8000 @ 1150MHz

Cellshock kit is known to be good to 1200MHz at least, so we have some headroom there. CPU tops out at 3.6GHz 1.45v without some real heavy duty volts (booo!)

So far I've tried increasing NB/SB voltage, changing to PL9, Setting TRFC as high as 60, trying different RCOMP settings, setting different refresh rates (currently on 4171, seems to be the best) Adjusting FSB voltage and setting NB skew to 200ps, none of that got me 500+FSB :cussing:

Any suggestions guys or am I flogging a dead horse here?

i got 500fsb with the dfi dk

I hope this mobo has a little more oomph in it than just 480........ I don't like the board but while I'm trying to figure out if theres anything I can do to make the BIOS better I do want to run a solid 500FSB at least. My Pro does 540FSB with this chip.. take THAT Biostar :down:

[Hondacity]

i sold my biostar ages ago...lol

i still have the dk..but no proc to test it with... get the gigabyte maybe you'll get 550fsb

I was given the TPower by members at this forum :up: partly as a thankyou for the work I've done with the P5Q series BIOS, and also to see if I could help the TPower shine more. If the latter can be done, I intend to do it :cool:

[mattkosem]

The TPower i45 should easily do over 500 without breaking a sweat. Memory settings set aside, what are all of your bios settings on the last tab and its sub pages? Here's a pic of the windows visible settings that I'm running for an FSB of 505 with my ram at 1215.

My relevant settings on the main page are:
Ratio: 9
FSB: 505
bsel:nb latch: 1333
FSB comp finetune: disabled
dram frequency: 1214
ddr2 enhance mode: enabled

My voltages are:
vcore: +.250
ddr: +.300
chipset: +.300
fsb: +.175
GTL0: .67
GTL1: .67
MCH GTL: .59

The other two pages are on the defaults.

weird because my E8400 does 500 fsb on the TP45HP without ever looking back 10 hours prime stable 530 fsb maybe you just havent found the right settings

QFT. Mine does 565x8 linpak 10-pass stable with the memory at 1:1.

Heres my settings. I have to keep DDR2 Enhance mode on or my Copy results in everest take a :banana::banana::banana::banana: to the degree of around -2.5GB\s

[mattkosem]

Have you tried playing with the RCOMP settings? I've had the best luck with 3. I also set my GTLs to .67 and set the MCH GTL to .59, but you're running an awfully high (seemingly unnecessary) FSB voltage. You might try setting your GTLs like mine and lowering your FSB to 200 or so. PLL shouldn't need to be over stock either. If that pans out, try playing with the RCOMP settings,

--Matt

[Ket]

Yep I have, for me RCOMP 1&3 simply = no POST. Heres a quick everest shot with memset. 45 TRFC is about as low as I can go to keep error-free @ 1200+MHz

ED - If need be I'm willing to pull an all-nighter to get the job done!

[mattkosem]

Are you able to push the FSB higher at a lower multi? The board really shouldn't be a limitation here. 514*7 should be easy. What is happening when you push the FSB higher? No post? Instability? Need more details.

--Matt

[Ket]

Massive instability @ 515FSB. I'm not sure whats going on with this system atm. A few days ago it would error @ 500FSB and not POST with RCOMP3, trying again tonight 500FSB and RCOMP3 are working fine :shrug: I'll be memtesting 508FSB in a bit. There really aren't words to describe how odd this is :\ low top speed or not, if I can do huge FSB figures, I don't care :D for some reason I have a real craving for loads of bandwidth. Also never underestimate the value of taking heatsinks off and letting air blow directly over the ICs on memory modules :cool: No cooling @ 1200MHz 2.27v = 18 errors, add a XTC memory cooler, same voltage, no errors.

ED - Quick everest bench 508FSB. Will report back after letting memtest do a pass

[mattkosem]

If it ends up being your memory holding you back, try bumping the R-W R-R W-W and W-R timings up a notch across the board. That change buys me an extra 40mhz or so with my current ram. My old ram only required changes to R-R and W-W to get stability at higher clocks, so if you have luck with the former give the latter a shot.

Ok, well 508FSB is a wall atm, thousands of errors in memtest. 500FSB (now at least) seems to be solid, does a memtest pass fine. Heat deffinately holds my unhooded Cellshock sticks back to a degree, they still get very hot. Thankfully the XTC cooler tames them well. I tried switching to 1:1 @ 508FSB to bring me down to 1030MHz (testing FSB limits) but the system failed to POST :\ you come across that with your TPower matt?

ED - Timings are tweaked a bit to 5-5-5-12-45.

I normally need PL9 or higher to post and boot at 1:1 with FSBs up there. Give that a shot. Don't be thrown off by the higher PL. Clock for clock, I've found that PL7 5:6 seems pretty close to PL9 at 1:1(and PL8@5:6 to PL10@1:1 and so on). This ram requires PL10 for 569mhz 1:1, and I see read speeds somewhere over 10k with write and copy both somewhere over 12k at 6-5-5-15.

[mattkosem]

Any luck?

[Ket]

None so far :( 500FSB still seems to be max stable but I can POST way higher, must be a setting somewhere thats not quite right.

[GeorgeStorm]

That is wierd, both the HP and i45 that I have used have both easily got over 500FSB, (well, not this one, due to my RAM, atleast, I think tis my RAM, maybe I have the same problem as you, ! it posts above 500FSB, but doesnt load windows, EVER, although I havent really tried....
(this is my first overclocked computer, and im gonna try your BIOS later today, :D

[Ket]

Ok, I'm pissed. 515FSB will just not get stable :mad: I've tried all kinds of tricks and this TPower is having none of it. I know my RAM isn't a major bottleneck, I've had it POST 1300MHz on my P5Q Pro, so I guess its just crap memory support on this board. I have to even make sure vDIMM is over 2v or the friggin board won't even POST, yet again on my P5Q Pro its happy to run 1.8v. On the plus side I've tweaked memory timings quite nice @ 1200MHz, just a shame the P45 shows little to no difference between 4-4-4 and 5-5-5 timings :rolleyes:
