x2 4000+ and emaxx mcp61s-avl shows wrong memory frequency?

[whoopz]

---

good day peeps, di ba if ddr2 667 ang imo gamit nga memory ky ang mugawas sa cpu-z is 333 (kay 333 double is 666 or 667)

in one of my pcs nga x2 4000 brisbane and emaxx mcp61s-avl mobo, ang mugawas sa cpu-z kay 301 raman (nya 301 double is only 602 which is far from 667) ngano ni?

but using the same geil ddr2 667 in another pc which has core2duo e6300 and msi p965neo-f, ang mugawas nga frequency from cpu-z is 333 (333 double is 667 and that is normal)

Whats the clockspeed sa imong processor karon? Basin naka underclock na' sya...

Otherwise.. naa man nay setting ang memory divider sa Bios... try playing around with those settings.

x2 4000 brisbane running at default clockspeed of 2.1ghz
(showing 301 memory frequency not normal)


c2d e6300 running at default clockspeed of 1.8ghz
(showing 333 memory frequency normal)

maybe your BIOS needs an upgrade. check with your mobo website.

I think I figured this out na...


Can you check CPU-Z for your memory divider? My guess is that its 7.


The way I understand it is..


CPU Clockspeed = FSB x CPU Multiplier... so (200fsb x 10.5X = 2100 ... 2.1Ghz)

Memory Clockspeed is a bit tricky. It also depends on your memory speed. (DDR2 667 in your case)

Memory Clockspeed = CPU Clockspeed / Memory Divider (2100 / 7 = 300 or DDR 600)
What I understand is that the memory divider must be a whole number as they cant do fractions....
The memory divider will be set to the lowest tolerable integer that does not result in exceeding your memory spec... which in this case is... 333 / DDR 667

So in a nutshell... 333 ang limit... and then 2100 ang Clock Speed... so whats the lowest number the CPU can afford to give you without going past the 333 limit.

Example... If we take the 2100 fsb / 6 = 350... which is higher than the memory spec (333)...
since this divider is too low.. your memory divider will go up to the next integer... which is 7.
2100fsb / 7 = 300... this is within the limit of 333... and mao ni reason why 7 imong divider and your ram is running at DDR600 or 300mhz

Lets say you buy DDR2 800 ram... which has limit of 400.... using the same example earlier...

2100 / 6 = 350... this is acceptable..... 2100 / 5 = 420... so dili pwede ang 5.... which means.. ur Memory Clockspeed will be 350.. or DDR 700.


In your case.. I suggest you raise your FSB to 220 and lower HTT multiplier to 4x ... this will allow your pc to run at 2.31Ghz and memory to run at 2,310 / 7 = 330... which is near enough to your ram's limit.

If you feel lucky and wanna overclock it a bit more.... you could try raising the FSB higher to 253., HTT 3x.. this will result in 2.656 Ghz clockspeed... a memory divider of 8 and still within your 333 limit.

Anyway... with the Integrated Memory controller of AMD...what really affects the benchmark results is raw CPU Clockspeed... memory running at 300 /DDR 600 won't really have a significant impact on performance... you can confirm this with Sisoft sandra's CPU benchmarks.

wow! great explanation bro, i completely understand. this was the answer i was looking for. salamat sa imo pag provide sa answer. yup, i checked the memory divider and it is 7.

Glad to help out bro... let me know if you're adventurous and wanna venture into overclocking. I'm curious to see how fast the X2 4000+ can go.

I tried O'Cing with X2 3600+ (1.9Ghz) and the highest stable speed I could get it at was 2.6Ghz.

I'm currently using X2 5000+ Black Edition and have the multiplier at 16x... with default fsb... running at 3.2Ghz.

great one.. informative!

[darkdevil]

very nice...
straight to the point solution...
heheh

nice unta but sadly dili man pang oc ako hardware ani nga pc bro. generic 500w psu, value ram, emaxx mobo, stock hsf. hehehe....


ive tried ocing my other pc, kato gaming pc nako. all hardware good for ocing except my mobo msi p965neo-f. with a core2duo e6300 stock at 1.8ghz my highest stable oc is only 2.3ghz which is a disappointment coz some people can reach 3ghz and above with this proc.
