Confused: Some explanation required

post #1 of 10

This is my rig's details:

http://valid.canardpc.com/show_oc.php?id=2302628


So, I am running Windows XP SP 3 and I am using 2x Kingston KHX8500D2/1GN, supposedly max rated @533 MHz/2.2V.

As you will see however, the individual memory frequency is actually 606.4 MHz, and the frequency given in the BIOS is 1213 MHZ. It's a 2:3 rate as I set it
in the BIOS.

After setting the memory thus, I noticed a tremendous performance gain in online video gaming (SW:TOR). I am passing through crowded areas and I am getting no lag at all,
it's sort of like I am flowing through.

My rig is dated 3/2008. Prior to these settings, I used to have the memory set to 1:1 ratio while calibrating my OC for maybe a week or so, and then throughout the remaining
period (almost four years) my memory was auto-set by BIOS to smt like 1250ish MHz (BIOS reported setting).

Now how is that possible again? Isn't the max frequency of the mory 533 MHz @2.2V? Am I missing smt here or what?

P.S: My memory underperformed substantially at 1:1 rating. 1:1 was 379X2 Mhz

I see.

So, since CPU-Z reports my 533 MHz settings as 5-6-6-15 and it's actually auto set to 5-8-8-28, do you think I should change that to 5-6-6-15 or that would
be an overkill given that my memory is already overclocked?

Thanks for helping out btw.

I think it would be overkill, but it won't hurt ot try smile.gif 5-6-6 i doubt, but 5-7-7 maybe smile.gif

Thanks again, mate. Turns out that my mem is already auto set at 5-6-6-15 in my BIOS, although CPU-Z reports it differently.

Anyway, Gigabyte (the maker of my ultra fail MOBO GA-P35-DS4), gives an OC Mem figure of...

My BIOS also lists upper memory bootsrap frequency as being 1333 MHz. Obv, it is not a good idea to OC my mem
at or near 1333 MHz, however, do you think it's a good idea to OC it further around 1250 MHz?

I understand "Bootstrap" to be some kind of limit. There are 3 such bootstraps listed in my BIOS, 800, 1066 and 1333 MHz.

At this point I think you'd benefit more from lower timings. DDR2 runs hot, and at high voltage. More OC can brick it. As of the timings- BIOS might report them as 6-6-6, but CPUz is the correct one, I think. Try to set them to 6-6-6 (or 7-7-7) manually and see if CPUz changes.

Now, as previously suggested, I reduced the frequency to below 1.2k MHz, and adjusted the settings manually at BIOS to 5-6-6-15. The Row Refresh Cycle Time (tRFC)
is somewhat too high at 60, but there is no suggestion from the manufacturer what to set it at.

Any suggestions w/ some justification pls?

UPDATE: best results I got after continuous tweaking and experimenting.

According to the results of SANDRA Memory benchmarks, a setting of 5-6-7-24-33@1066MHz, which is the lowest stable settings I got,
is actually BETTER than running 5-8-8-26-64@1212.8 MHz..

Although the RAM frequency and the Chipset FSB speed as well as the Chipset Max Memory Bandwidth is greater in case 2, my memory actually
had SUBSTANTIALLY MORE LAG, i.e. it was SUBSTANTIALLY SLOWER than in case 1, wherein I am shown to have lesser RAM
frequency, less Chipset FSB speed as well as less Chipset Max Memory Bandwidth.

(Note: "Chipset" means my Intel P35 MOBO chipset).

Conclusion: Tighter Memory Settings & running at Max Rated Frequencies for your RAM is faster than looser ratings and OC
frequencies greater than the max rated ones for your RAM.
