ahh i see
i knew i should have grabbed that 2x2gb 1066 ram that went for £35 on here

 

[JrRacinFan]

Here I will try to get a 4Ghz run real quick. Nope, this chip won't do 4Ghz. Gave it all the way up 1.5v.
Here's a run at 3.9 though

wow you have your pc clocked abit lower and the nb much lower,thats a hefty tdp!
could performance ram make that much difference?

TDP reading is false. It's due to the core unlock. Yeah, the ram speeds do help alot. Yours beats out mine because your NB is higher but my ram is clocked a touch higher with better latency.

So much for NB speed...

[MightyMission]

i got an extra 23 whatevers by upping the nb to 4ghz and the fsb up 1,hardly seems worth it-maybe my ram is the bottleneck now?

i would bet, that it is
just compare our benches... your CPU scores are higher due to 4ghz... but my memory and streaming scores pull you out of the water

 

[MightyMission]

haha!
It's no biggy - the computer still runs alright and does what its supposed.
this is going to be one of those things that gnaws at me now,do i waste upgrade funds a few months before bulldozer or do i be happy with what i got.
Damn benches!!!
at least i proved i wasnt blagging about the computer,wether its fastest or not is immaterial i guess as theres always someone a few more steps up the ladder

maybe try to equal your clocks and timings, so your NB doesnt get starved out by your memory?
cl5 would be a good beginning
and... there is still about 100% of memtest till stability
(Overclocking without speed gains, is nonsense, then id rather go for undervolting with good clocks)

 

[MightyMission]

yes i did ask you further up have a look ^ which was the right memtest?
there clearly is gains though,check the stock and occed results.
i will have a look at timings now.

 

[JrRacinFan]

Here. This will help you.

Run MaxxMEM and try to get those numbers to even out.

Or AIDA64 Memory and L3 Cache read

As you can see I am overkill on NB for my ram clock but if I go one notch down then it won't be fast enough and ram would be bottlenecked by NB.

 

[Velvet Wafer]

sorry, i overread that... yeah, this memtest you showed is correct, its the one i also use
i think most gains you get, are thru the 4 ghz main clockspeed, and the high NB probably looses most of its benefits after 2400mhz NB according to your memory clocks/timings... as said, your CPU got a good amount of points more than mine,in integer and floating point... but memorywise.. no chance... and NB is speeding up Memory and L3 Cache normally, when clocked, not only the L3 cache

 

[MightyMission]

i lowered the timings to 5-5-5-15 2t and it only gave an extra 50 whatevers,though i think it wont be far from bsod.
is it worth going for 1t ?

you tried for more bandwith, by upping memclocks, opposed to changing timings?

this is how it looks for me, and that is pretty much balanced NB/Mem:

 

[MightyMission]

no i lowered the timings because if i up the memclock it wont boot?
i am not clued up on this at all,as said before benches arent my thing.
the timings are figures of latency? so i thought less latency=faster response=higher bandwidth?

Don't bother with 1t, try loosening tRFC all the way to 195ns and push for bandwith. Bring your NB down and just a touch of info. Multiply your dram clock by 3(ddr3) or 5(if ddr2) and thats where your CPU-NB should be about. Say if you got ddr2 @ 600(1200 effective), it would best run with 3Ghz NB, whereas ddr3 667(1333 effective) would be best ran @ Stock (2Ghz) and gains would be minimal if raised.

so i thought less latency=faster response=higher bandwidth?

Also think of it as cycles (timings) versus how much data can be pushed through at one time (bandwith). (I think)

so, maybe back down the NB, and try to clock your memory further... it will give you bigger speed gains then just sitting on a very high NB, that gets bottlenecked by its slow ram
low latency for DDR2 on Phenoms does not yield as much, as low latency on DDR3, where the bandwith is much higher, naturally

Also think of it as cycles (timings) versus how much data can be pushed through at one time (bandwith). (I think)

Thats completely right, from what i have understood of how it works

Thanks for confirmation VW. I have lost my mojo lately and cant remember crap.

These Times are difficult... the World is shifting towards big changes... it pulls on us all
Therefore we are here, to help each other.... you forget how Rigs work... i forget how to divide numbers on paper... someone else told us again

this cpu has a fsb wall at 278,or maybe its the mobo,either way i am only a few fsb notches away from it and i know that 277-8 just offers me bsod,which is why i dont bother going that high for what it gives back.im just glad the mobo has a reset cmos button on it
http://img.techpowerup.org/110331/maxxmem.png
thats the maxxmem

random question,would ecc memory affect the output?

 

[JrRacinFan]

No it wouldn't but it is possible it would effect your overclockability. For now, drop your nb a couple multipliers because at your speed you only need ~2.4Ghz NB. Save yourself some heat and voltage to the cpu, never know you might even be able to push that cpu even further in HT speed .

 

[MightyMission]

mm i think i got 4.2 at the cpu with stock nb and under rated ram but the higher nb gives more of tangible results,plus its much more stable than the high cpu overlcock.regardless of the numbers im pushing-though this has been educational.
EDIT
Jr:i changed the maxxmem to high priority,the same as yours is,and the figures are much closer but of ocurse yours is still doing a heap better.

its a mobo wall, nearly all phenom 2 AM3 should do 300 on the right board. mine needed 3 boards, till i found that out.

here is my Maxxmem, for comparance:

you need an equal combination of all system speeds/clocks... then run 25 runs Linx Linpack, and 100-200% memory stability in Memtest... and then you know you got your system maxed out, without bottlenecking any component, and at (nearly) absolute stability

 

[MightyMission]

I dropped the nb to stock to see what more i could get from the ram and i got some odd occurences!
no POST cuts the long story short
That maxmem screeny is a heap faster still!

I chose an nvidia board for my 945 because i didnt intend to overclock my computer,until i see it was very easy to get free performance increases.

I understand nvidia boards dont overclock so well as the amd counterparts,and i wish i would have got a crosshair 4 at the time,as it would have an all in one block on it by now.

It has been a long day so i will have a look at balancing all the speeds and clocks out then running the various apps for testing when i next have a few hours.
thank for the help!

well thats just wrong my first phenom II board was the Asus Crosshair II NV780A and it managed a 400+ MHZ HTT and 5ghz. gotta say it must just be you or your board

looks normal to me, how are your NB and memclocks?
