Phenom 9500 w/ MSI K9A2 Platinum

[tictac]

if you cant boot with 18x nb speed that mean nbspeed is actually working on your board. actual with non-be phenom max nb multi is 9x. the nb speed multi will still remain at 9x eventhough you set it higher. that mean it will bootup even we set it to 18x. but yours wont. got it?

And I probably won't be able to hit 3.5ghz, my htt maxed at 300 when I tested it on this cpu the other day. That would only give me 3450 at most, which would be amazing for a phenom, but even just 2.9 at 1.3v is giving me 50-51C load with small fft's, meaning around 56-57C true max.

Well, I guess I'm one of the few that can play with the nb multi. That and anyone else with the 0801 bios for my board.

This is Phenom 9500 (max nb multi = 9x) with 5.6GHz NB speed... it boot up ... Biostar TA770.... i guess it is not working.. because if it work it wont post at 5.6GHz NB speed....



but benchmark show improvement over slower NB speed.... i am still wondering why...

What's it showing for your cpu speed though?

Edit: I just started trying 267*11.5. @1.3v it failed prime on the first core in 6 seconds, @1.325v it failed in 55s, and @ 1.35v the last two cores don't even start. I just realized I had processor to nb voltage left on auto, set it to 1.3 and I'm gonna see what happens next. Oh and if this setting doesn't work I'll at least get a screenie of 3ghz stable with 1.3v.

That is polygon aka rebelheaven rig... you can refer his post here...

Here's what I remember getting last time I was running benches

Everest Cache and Memory

L1: 1.0ns
L2: 3.0ns
L3: 6.5ns
Memory: 57.4ns

Your NB speed is 9x looking at your RAM latency, it should be below 48ns if NB was actually plus 2.4G but your L2 cache is too low, lower than real 2.91G Phenom gets. 2.91G gets 3.3s which means you're at plus 3GHz CPU speeds as that's all that effects L2 latency.

What RAM MHz/timings does CPUZ show at those settings?

And I probably won't be able to hit 3.5ghz, my htt maxed at 300 when I tested it on this cpu the other day. That would only give me 3450 at most, which would be amazing for a phenom, but even just 2.9 at 1.3v is giving me 50-51C load with small fft's, meaning around 56-57C true max.

Cold limits are many times different

Well, I guess I'm one of the few that can play with the nb multi.

You see, so could everyone else I've seen incl. myself and look at tictac's post above mine. It's just that Phenom 9500/9600 did not actually change NB multi plus 9x. Only CPUZ would show it higher speeds than 9x and real software would show you the speeds.

BUT... but... divide the NB speed AOD shows by the HT ref. you set in BIOS at bootup and I bet it shows the NB multi at 9x.


BE does change NB multi and shows NB speed having big difference on perf and you need high NB volts for that.
*If you want to find out and see for yourself, like I said, just bootup at 266x11.5 3.059G at 9x NB multi and your scores will be like you're getting above, probably even faster.
-Then set to 239x11.5 2.749G and 11x NB multi in BIOS and compare 1M/wpime with your above "2749" scores. It will be a lot slower.
-Then set 217x11.5 2.495G and 11x NB multi in BIOS and compare with above "2530" scores. They'll also be a lot slower.

Not because you didn't oc your NB, you did here too but because your NB was always at 9x and your CPU speed was much much lower in these cases than the shots you've already posted.

You're not setting 2.7G/2.5G in BIOS, you're setting 266x11.5, that's why CPUZ is reading 266x11.5 3.059G.
If you set BIOS at 2.7G and 2.5G, I'd like to see that.

TRUE NB multi moved up above 9x is shown by one clear way: Sandra mem/1M/32M/wprime/RightMark MTMT and most importantly, you can validate the CPUZ (you can't otherwise) and you'll also be able to move HT up to those speeds too. Like this:




If no NB multi change above 9x, AOD does not allow higher than 9x HT multi on any Phenom.

Easy tests to prove NB/CPU speeds:
Run Cinbench 10 and POV-Ray 3.7 BETA at (BIOS values):
228HT ref. x 11.5 CPU multi (2622MHz) and 9x NB multi (2052MHz) ->
THEN
Again run at 228HT ref. x 11.5 CPU multi (2622MHz) and max NB multi (if 12x then 2736MHz) ->

Post back the images and scores.
Show both, AOD and both CPUZ CPU/MEM tabs in the image.

This is Phenom 9500 (max nb multi = 9x) with 5.6GHz NB speed... it boot up ... Biostar TA770.... i guess it is not working.. because if it work it wont post at 5.6GHz NB speed....

Hehe.. that's crazy. What benchmarks have you tested? Can you run the above two tests for me at 9x NB and at your max NB multi?

[Oldguy932]

You're not listening. Here is the complete breakdown.

HTT=HTT set in bios
NBM=NB Multi
NB=NB Speed
MEM=Memory speed
CPU=CPU Multi
CPUS=CPU Speed

NB=9*HTT
MEM=HTT*divider
CPUS=(NB/NBM)*CPU

I know the actual NB speed cannot go above 9*HTT on a regular Phenom. What happens on my board is that it calculates the NB speed before the cpu speed, and because it lets me change the NB multi above 9, the htt the cpu is based off of is different than what is set in the bios. I'll make some tables in excel in the next couple days or so to show you what I mean.
