GA31M-ES2L<-- Is this OC able?

Re: GA31M-ES2L&lt;-- Is this OC able?

I was thinking that but Chike wants to swap CPUs for a trial run so I may end up with his e7500, we'll see....

Re: GA31M-ES2L&lt;-- Is this OC able?

Maybe time to grab a X38, X48, P35 or P45 instead of this board?

It is time to grab Z77.
I have tried to look for cheap boards and there are none. Everyone that has them think they sit on a gold mine.

Re: GA31M-ES2L&lt;-- Is this OC able?

I did some checking the other day but P35/45,etc boards are around $100 and I'm not sure if it's worth it....Hitting 4ghz would be fun but with Chike's e7500, 3.66ghz at 333fsb would be easy and hopefully I could even push it a hair more towards 3.8ghz. Not sure which direction I want to head after this, iCore, some newer AMD setup, ????

Either way, I really like GB boards and hope to hang around either way....

Re: GA31M-ES2L&lt;-- Is this OC able?

Alright, just a quick question. I'm for now running a modest 3.25ghz at 1.26v (in CPUZ) but have lousy performance results in IBT gflops. Gflops are only around 19-20 (43-44secs). My ram at 2:1 is only running 648mhz so should I tighten up timings a bit more? Right now they are 5-5-5-15 with DDR2 Overvolt at +0.2v. Other timing specs are still set to last screenshots. Bumping spd to 2.5:1 would put ram freq at 855mhz but I guess 2:1 (actually 1:1 ratio) is better for OC?

Just hate this stupid FSB wall and with PCI set to 100, this is the limit with this cpu/board. I may try higher fsb lower multi but I doubt it'll work. What about a bsel mod?

Can you post full settings with MaxMEM results?
Lets see if there is room for improvement.

Re: GA31M-ES2L&lt;-- Is this OC able?

I think you will be able to lower timings to 4-4-4-12 at DDR-684, try with both DDR2 OverVoltage +0.3 and +0.2.
If this works try lower tRD (lower CAS enables lower tRD).
I will later boot with Windows XP and see what I get there.
20.4GFlops is about what I would expect(20.8) from the OC based on the baseline IBT you ran.

[Chike]

Re: GA31M-ES2L&lt;-- Is this OC able?

After reviewing my baseline against my 3.25GHz Flops, and yours I'd say your Flops are just fine.
Numbers are from the top of my head.
3250 / 2533 = 1.283.
Yor base Flops 16.2, expected at 3.25GHz 20.78 actual 20.40, 98.4%.
My base Flops 16.7, expected at 3.25GHz 21.43 actual 21.18, 98.8%.

It's all good don't sweat it.

Re: GA31M-ES2L&lt;-- Is this OC able?

Ok I'll try it out...btw, is it best to leave PCI at 100? I've read 100 is the only number to use and I've read up to 105 is safe. I don't want to compromise hardware reliability or risk damaging anything....

[Chike]

Re: GA31M-ES2L&lt;-- Is this OC able?

I don't know i don't mess with the PCI clock just leave it auto or 100 which is the same.

[aggiefan]

Re: GA31M-ES2L&lt;-- Is this OC able?

Well after setting PCI to auto the other day and running a 350-366fsb (can't remember which exactly), setFSB showed actual PCI frq to be 106...auto is kindof goofy on this board I guess.

Tighter timing values:

Re: GA31M-ES2L&lt;-- Is this OC able?

Yes, auto is not 100 always, it just looks that way in easytune!

Setting 100 manually will limit your overclock to whatever is bootable with 100, get what overclock you want with it in auto and verify the clock with SetFSB.

Then set that value manually, or decide if you want to have it that high or not, if not you'll have to lower the overclock.

[aggiefan]

Re: GA31M-ES2L&lt;-- Is this OC able?

Well that's my question, how high is safe for longevity? I hit close to 3.5ghz with PCI on auto but FSB was between 106-110 so I didn't think it was worth it but I don't have the experience of you fellers....So keep it at 100 or push it?

[Lsdmeasap]

Re: GA31M-ES2L&lt;-- Is this OC able?

I would say keep it under 108 for 24/7 use, much above that may be pushing on your other hardware too hard (Not the board or CPU).

I've ran 103-108 for a long time with no bad effects, so you should be fine as long as you don't push it too far. If you do, you'll know when your hard drives start dropping out or LAN starts failing, but that's usually at 120+

[aggiefan]

Re: GA31M-ES2L&lt;-- Is this OC able?

Ok, I'll give it a shot, something under 108....I might be able to get up to around 350 that way, maybe 366. Need something to try until Chike's 7500 gets here, unless it's intercepted lol...
