mATX and E4300, any OC results yet?

[FlukeDK]

Anyone tried a E4300 on mATX yet, and what was the outcome?

[Warship]

Wondering the same myself. Was kinda planning on exchanging my E6400 for an E4300 and run it 9x300

[PÿRÓ]

Same ..waiting to see what the Gigabyte GA-965GM-DS2 is like ?

[pvhk]

the last bios allows at last overclocking settings!
this mb can handle up to fsb320! (i965g chipset limitation)

[Rogosh]

I have a e4300 right now and my Biostar I945G-M7 v2 is coming next week. will post results. Max fsb supported by mobo is 300 but id be happy with 9x300 on a dual core for everday use on air. Did some searching around and it supposedly has a pci / pcie lock so im optimistic to reach 300x9.

mATX Conroe's can't go past 350 FSB

[__Miguel_]

As far as I've seen and read about OC'ing, it seems the Intel 945 chipset line has a rather "iffy" PCI/PCI-E lock, meaning it actually doesn't lock all that well.

The consequence of this is that many devices begin to suffer at very high (for that chipset line, mind you) FSB speeds, usually above 300MHz (I think it's above this value the PCI/PCI-E locks begin to fail). Try searching the forum, I remember reading something about it not so long ago...

I would, therefore, recommend G965-based mATX motherboards for serious OC'ing. Of course, the problem then is to actually FIND a G965-based mATX motherboard with decent (if any at all) OC functions... Any guesses?

[EDIT]Ok, I didn't read the thread correctly. I swear I read the Gigabyte model as 945, not 965 Meaning the 945-talk, albeit valid, is somewhat not important, since we're already talking about 965-based motherboards. Sorry about that.

In any case, probably the 320MHz limit on mATX boards, provided there are voltage controls, may come from the IGC (Integrated Graphics Core), which, if memory serves me right, is based on "only" 90nm tech on 965 chipsets (and 130nm in 945).[/EDIT]

945g outperforms 965g when it comes to overclock c2d!
965g hits a wall around 320
945g can handle fsb up to 350!
However, the new e4300 cannot be recommended today with matx 945g/965g
because it is simply impossible to raise the fsb (Nb strap issue with c2d fsb800)!
tested on P5LD2 VM (945g) & P5B VM (965g)
The c2d fsb1066 is not concerned...
the only matx which works for the moment with the 4300: asrock 775i65g

[renethx]

E4300 works fine with ASUS P5L-MX (945G) at FSB 1300MT/s = FSB 325MHz = CPU 2.93GHz.

E4300 Overclocks? at AnandTech Forums

i just got a 4300 setup 2 days ago
it is running happily at 2.65GHz on stock voltage
i havn't tryed to go higher yet as i don't wanna lower my ram speeds and am happy with this speed for now
also my board doesn't have vcore adjustment for some reason ... ASUS P5L-MX


i just updated my bios to the latest and pushed mine to 3.1Ghz on default voltage
tryed 350fsb but it wouldn't post right even with lower mem speeds
this looks like the limit for my chip without more vcore and/or better cooling
possibly the chipset/motherboard's limit also


i had to back down to 2.9GHz to be stable
the problem for me definately appears to be the motherboard not liking fsb speeds over 1300Mhz
if i could set the clock mult higher the cpu would almost certainly function over 3GHz stable

[pvhk]

Very strange!
although the 6600 works fine on p5ld2 VM DH @3150 (fsb 350)
the e4300 on this same mb does not allow any raise of the fsb over 200!

on an other forum: the p5l mx seems not to be overclocker's friendly

It's not mATX but Gigabyte G965-DS3 is almost as good as the P965-DS3:

Pros: Nice features, high overclockability.

Cons: First board was dead, no post on boot. Heard many issues of ram voltage too low for high-end memory, but Corsair CM2X1024-6400PRO worked like a charm (once I got a good board).

Other Thoughts: Right now I'm running a E6300 (1.86Ghz) at 3.22Ghz on stock cooling. By far the best overclocking I have ever personally done.

Biostar P4M890-M7 does 336MHz ( for a Via chipset...)

[pvhk]

e4300 is not the perfect match with 945g (P5LD2 VM DH or VM SE)!
This C2D fsb800 is locked @200 and any attempt to set fsb over 200: 201-265
results in overclocking failed!
There is no way to change this! (maybe the BSEL mod)
This phenomenon does not concern hopelessly the c2d fsb1066....
The same behavior is reproduced on the P5B VM (965g)!
Be warned....

On the contrary: the e4300 + asrock 775i65g is the perfect match on matx :

Maybe our savior!

Thxs to ABO-san

[pvhk]

My beta test with the P5LD2 VM SE (PLL =IDT CV122C) is now completed, and the soft made by ABO-san is now fully fonctionnal!
The new revision is now available for download!

Very gratefull for this outstanding job, ABO!

I think that guy might have posted his comment in the wrong board. No way in hell he's up that high with g965. Just not possible.

pvhk, looks nice!! What's the highest it'd boot from bios settings? It's a miracle you don't lose sound, nic, or sata up that high.

[pvhk]

sorry for the late answer!
fsb@340 & PCI@115: no sata issue. PCI locked@33.3

The BSEL mod works on Foxconn G9657MA-8EKRS2H + e4300!
A guy managed to bump the fsb over 266:

[pvhk]

without BSEL mod with my abit fatal1ty f-i90hd:



keep in mind that the samples distributed in europe although retail in appearence come with their bios mentionning "not for sale"!
This may explain why this mb is not available elsewhere until maybe today..

[pvhk]

windows in action!

[__Miguel_]

Impressive, pvhk. That may just be the fastest m-ATX board available for socket 775 ever made... And one of the coolest-looking ones too (and that coming from someone who isn't that fond of red...).

I'm drooling already. I've got to know, how long till they hit the shelves. And, mor important, how much will one of these babies set me back? I'm saving up already... hehe

Cheers.

My experiences:

-ECS P4M800Pro-M v2.0 (mATX), BIOS 061214: displays a warning about the FSB on boot, but allows the user to continue at 266MHz

-Gigabyte GA-965GM-S2 rev1.0 (mATX), BIOS F2, F4: does not even POST.

Still hoping for a solid mATX board that'll take this mod.

EDIT: A more in-depth testing of the ECS P4M800Pro-M v2.0 at different FSB OC settings; this BIOS has a cap of 300MHz FSB in call cases, and "warning" refers to the message about the FSB of a modded CPU at boot (which requires a Y/N choice the first time, and then simply displays the warning afterwards):

Unmodded E4300:
-Disabled: boots at 200 with no warning
-200: doesn't even POST
-201-231: boots at FSB with no warning
-232-265: boots at FSB with warning (at 265 FSB, Sandra showed the AGP bus at 88MHz)
-266: boots at 200 with no warning
-267-300: boots at FSBs between 201 and 225 with no warning (at a setting of 300 and an actual FSB of 225, Sandra showed the AGP bus at 74MHz)

Modded E4300 (insulated BSEL1, traced over BSEL1 tape with run from BSEL2):
-Default: boots at 266 with warning
-200: doesn't even POST
-201-215: boots at FSBs between 268 and 286 with warning, seems tentatively stable at +.03V CPU (effective 1.324 Vcore), unstable at +.02V and below
-216-239: boots at FSBs between 288 and 317 with warning, unstable even at +.03V CPU (probably Vcore-limited?)
-240-265: doesn't even POST
-266-285: boots at FSB with warning, seems tentatively stable at +.03V CPU (effective 1.324V Vcore), unstable at +.02V and below
-286-300: boots at FSB with warning, unstable even with +.03V (probably Vcore-limited?)
(Sandra never displayed an AGP bus clock speed when the E4300 was modded)

Unmodded E6300:
-Disabled: boots at 266 with no warning
-200-265: no option for booting below 266 with an E6300
-266-300: boots at FSB with no warning, seems stable

Modded E6300 (insulated BSEL1, traced over BSEL1 tape with run from VCC):
-Disabled: boots at 200 with warning
-200-265: no option for booting below 266 with an E6300
-266-300: boots at FSBs between 200 and 225 with warning (at a setting of 300 and an actual FSB of 225, Sandra showed the AGP bus at 74MHz)


I tested these all with a 1GB stick of DDRII-667 RAM, set to the lowest memory multiplier in the BIOS. While instability was readily apparent, I make no promises about statements of stability, as I didn't have the time to run Orthos Prime95's Blend for more than a couple of minutes for each of these cases. I'll admit, I don't recall the previous P4M800Pro-M I tried going as high as 300MHz with the E6300, so some of these values should probably be considered YMMV.

Anyway, it seems like the most I can get out of this board and these CPUs is a modded E4300 at 9x285MHz = 2565MHz or so, about a 43% overclock. Sandra couldn't gauge the AGP bus in that case, but I figure that if at 266MHz FSB AGP should be 66MHz, then it should be at a 1/4 divider and it's probably running around 71MHz, which doesn't seem that out-of-spec, so I'm guessing the instability I saw beyond 285MHz is more an issue of the paltry Vcore options...? If that's the case, the manual pad voltage mods might help out; I'll probably give that some effort when I get some time.

For a chintzy ECS board, I guess 2565MHz from a 1.8GHz chip isn't so bad...

EDIT 2: Should also give my week and code--Q641A268--to put the numbers in perspective.

EDIT 3: Tried one of the pad mods to override the CPU voltage--specifically the one VR-Zone pegs as 1.55V, though the BIOS showed it more as 1.5Vish for my particular CPU--and was able to run Orthos Blend for a couple of hours on the modded E4300 at about a 306MHz FSB (set to 228 in the BIOS) x9 = about 2754MHz. I don't know that I'd want to run at 1.5V around-the-clock (it was just the easiest of those mods to tape off quickly), or even if 1.5V is actually needed, but it does at least seem to indicate that Vcore is a factor for my particular CPU. As usual, ECS is typically pretty limited through the BIOS in this regard, so people trying to make the most of the board would probably want to look into forcing a voltage through the pads.

Check that post

[bob511]

Since it's not clear from that quote (from the BSEL mod thread) that the GA-965GM-S2 fails to POST with the modded E4300; it boots fine with the unmodded variety, but just doesn't OC enough to really be worth talking about.

I wrote Gigabyte to see if they'd consider adding support for/removing the whatever checks on the BSEL outputs they have in their BIOS at present, and they said they'd forward the request to the BIOS devel team, but I'm not holding my breath.

@pvhk
Does that board have LEDs on it?
Can you post some pictures of it running please.

Abit f-i90HD:
fsb@340 vcore@1.47 vNorthbridge@1.944v:


The question is: does it have the PCI-E & PCI lock compared to all other matx boards available?
The answer to come soon, thxs again to ABO san great work!

that abit really looks nice.
ironicly AMD has the best chipset for mATX C2D boards
