Lower multiplier even worth it? Check it out! - Page 4

Poll Results: Is it beneficial to lower the multiplier on your CPU?

 
  • 39% (16)
    Yes, definatley gives me more performance.
  • 19% (8)
    Yes, but not for the above reason.
  • 12% (5)
    No, too hard to find my best overclock.
  • 2% (1)
    No, but not for the above reason.
  • 26% (11)
    I have no clue.

Yes, definitely gives me better performance.

This is especially true of Intel's Core architecture. My E4300 with do 3.1GHz on either the 8x or 9x multi stable, but due to the higher FSB (and therefore higher memory bandwidth), I see a noticeable increase in performance when using the 8x multi and a 388FSB.

In the end of this all, it's going to come down to individual systems and components. Some systems will greatly benefit from dropping the multi & letting the FSB scream, other systems will not be capable of this, and the overall performance will be hurt due to instability and the inability to reach the higher overall speed available with the higher multi. Certain mobos are not capable of pushing a 400+ MHz FSB due to northbridge constraints, others will be at the mercy of their RAM's capabilities.

However, when all else is equal, a lower multi with a higher FSB at the same speed as a system with a higher multi & lower FSB should ALWAYS have better performance, as long as it's stable.

In some cases, yes. In mine, I won't believe it until I see actual specs run on a system just like mine with the exact numbers in my case to prove it.

When I get around to it, I'll tell you what I'll do. I'll make four 3DMark06 runs with my system at each case:

400x8 FSB, 3200 MHz, with RAM in "Sync Mode". (this is my current setup in BIOS).
356x9 FSB, 3204 MHz, with RAM set at 800MHz.

I'll report back. I really don't have time right now... I have to run some errands, and I've been busy lately with work (and the woman)... but I promise I will do this in the near future.

How does that sound?
Your a fricken hero man, really. Thats the only way to really test it. Just to have you know, I've been playing devils advocate, cause I honestly don't know. I was just fighting for the other side of the argument.

With that test, we will be able to see if a higher Memory:FSB ratio outweighs higher FSB, or vice versa. Until then, I don't know what to think, so get to testing. I'll run the same test as well.

As for me, I have to get off this dang computer. My eyeballs hurt and I can't think straight...

Thanks. Sorry if I come off as a little defensive and obstinate, but I've had the same argument with a few other folks that didn't remain so "adult-like" (my fault too, though).

I completely agree with this: if you can get higher Memory speeds by creating a divider because your FSB cannot handle it, then by all means do it. The increased memory speed will more than likely make up for any drawbacks of running your FSB and RAM out of sync.

But in my case (where my FSB is matching my RAM) I think I can get higher scores without the divider.

I'm going to be glad when I can get this testing done... maybe I'll prove myself wrong (hope not) . Either way it will be good to know.

PS: to you, too.

Tagged for outcome. While you're at it could you try a SuperPi 1M run at each setting also?

You may find this funny, but I've never ran SuperPi at all. I guess there is a first time for everything. I'll see if I can do this as well.

Oh, wow, really? It will show even the slightest increase/decrease in performance as it times each calculation down to the millisecond.

There is a link in my sig for the download. It's a very small utility (60.4kb).

You were not at all defensive.

I am going to run these tests too. I personally am not on either side, so more power to ya if your right. I just wanted answers, because for some reason I must understand everything, and even little things like these bug me to insanity.

I'm serious, sometimes I wish I hadn't even got a computer because of it. lol. I'll post up with my results too. Make sure to keep everything else in the test constant!

I think the base out come for this study will be that regardless of multi or CPU FSB, however you can raise your stable RAM speed and increase memory bandwidth, the better off you are, be it through a 1:1 ratio and lower multi, or a higer multi/lower FSB/memory divider.

Bandwidth is king.

Okay, I'm about to commence testing after a long trip to town (lame). I have to be somewhere at 9:00, so I should have more than enough time.

To be fair, I'm going to run:

4 Tests - 400x8 @ 3200MHz, with RAM at Sync (800MHz) (1:1 FSB:RAM)

and 4 tests - 356x9 @ 3204, with RAM set at 800Mhz (using Divider)

I know the Divider tests will be run with a 4Mhz advantage... but since I believe the Sync tests will win I'll run the divider tests at 3204, instead of 355x9 (3195Mhz). The 4Mhz should be negligible anyway. It's not perfect but as close as I can get it right now.... or... suggestions?

Sound ok? I'll be able to post and the whatnot while I'm doing it because I'm typing this on my alt rig. (Athlon XP FTW, lol)

All other options will be the exact same. Nothing else with these tests will be different from each other except what I've stated above.

Sound fair guys? Any Suggestions before I begin?

EDIT: When I've gathered all my results, I'll post in a new thread with my data/findings.
