e2140(m0) I think a Q733
400x8 3.2G
1.4025v bios

I'm having serious issues with overclocking.

I've got an E2160 (SLA3H) and it won't do more than 2.34GHz (260x9). I'm using a Gigabyte GA-945GCMX-S2 which was on the recommended motherboard list which is stickied at the top of the motherboards forum. I'm running at 1.35V. My memory is locked in at 866MHz with no problems. Memory is OCZ Vista Edition Gold (2x1GB).

I've tried cranking it up to the 275MHz bus and nothing. I've even tried the 300MHz bus (memory was clocked below 800MHz using the dividers in BIOS) while cranking it up to 1.45V core and it won't even post.

I'm using a Thermaltake W0070RUC TR2 Series 430W PSU and a massive Cooler Master Hyper TX 2 cooler. I don't have much stuff in my rig (200GB, DL DVD Burner, 7300 LE)

My idle temps at 2.34GHz is 32C and 47C under load. WTF is going on?

FWIW my E2140 that hits 2.8GHz on my IP35-E refused to go over 1.86GHz on my Gigabyte 945P-S3, which is also supposedly good northwards of 300FSB. It may require a BSEL mod to work properly (NB strap issue?) but I didn't want to bother and instead bought the IP35-E for maximum OC. I can hit 3.0GHz but it's not stable as I run F@H all the time.

I'm not going to upgrade again until there are sub-$200 overclockable 45nm quad cores. At this point my X850 XT is my bottleneck 😛
 
I've got another rig to add.

E2140 (M0) @ 3.28Ghz, 410 x 8
1.425v (BIOS), 1.36v (load, CPU-Z)
CoreTemp reads 66C, TjunctionMax 85C, may be 15C off
4x1GB SuperTalent DDR2-667 @ 820, 5-5-5-15 (can also run 4-4-4-12), 2.0v vdimm
GA-P35-DS3R, F9 BIOS
CoolerMaster HyperTX 2

Edit: make that two rigs, same thing, except 2x2GB Patriot DDR2-800 5-5-5-15 memory.
 
Here's mine to add, E4500 running 3.3Ghz, 333x10, @ 1.42v VID, 1.38v vDroop load. with water cooling, 50c at load. Also have hit 3.67Ghz with 333x11, @ 1.6v VID, 1.57v vDroop. I think if I drop multiplier, and raise FSB, I can potentially transfer some stress to North bridge, and lower stress on the CPU itself. I've yet to try 400x9, but I will during Xmas break. Normally I run the rig at 3.0Ghz since it does everything I need it to do, photoshop, surfing, and gaming.

A faster FSB really doesn't do much for performance. A 400FSB will probably only be 1 - 2% faster than a 333FSB.
 
Would it matter if the memory is running at 333FSB (DDR2-666) or running at 400FSB (DDR2-800). Or does it matter if I make memory run faster using 5:6 divider? If not much of a difference, I'd rather make the memory run at DDR2-666 spec and with tighter timing over DDR2-800 spec.
 
5:6 is slightly faster than 1:1, but we are talking VERY marginal gains of around 1% give or take , only noticeable in benchmarking, it has no real effect on 'real world' performance. The main exception to this rule is WinRAR performance, it scales very well with RAM/FSB bandwith, so if you work with a lot of big files in WinRAR it may be worth it.

 
I wonder if I should just go for 1:1 ratio, and use 4-4-4 instead of 5-5-5 timing. Would tighter timing make it worthwhile even though running at lesser RAM bandwidth?.

By the way, I'm using 2x2GB of DDR2-800, but it'll only let me use Command Rate of 2, even though I select 1 in BIOS. I think the limit to 2 Command Rate has to do with having higher memory density.
 
to all who posted 4xxx rigs:
how come all of you have vcores around 1.5v?

VID is the same for the 2xxx

is it that you with the 4xxx don't run that vcore all the time (just ran that vcore for OC)? or is it that you think vcore up to 1.5 is safe to run day to day?
 
@ Zach... don't know if you're still adding but if you are, kindly add me to the list:

E2180 @ 3.25ghz (Batch Q709A616, Pack Date 9/1/07)
325 x 10
1.465v
Abit IP35-E, Bios 14.B05
3GB Ballistix (4 sticks) PC2-6400 @ 4-4-4-8, 1:1.25 divider, 2.05v
Tuniq 120 + AS5 (Idle 24c / 58c Orthos Blend)

18hrs memtest86, 9hrs 44 mins Orthos Blend stable (stopped by me)

Gundam, you should have a look at page 99 of the Abit IP35 mobo thread where I have posted some RAM timing tests:

And also in the System RAM forum too, a great little thread as well:

Tightest timings/best divider on IP35-E

 
E2140 @ 3.208 Ghz (L2)
8x401 Prime95 stable.
1.405 VCore in bios.
Abit IP35-E
2 GB CORSAIR 6400C4DHX 4-4-4-12 2.1v DDR800 (barely fits).
Cooler Master Geminii & 2 slow 120mm CM fans, white goop.

Very happy to get a 100% overclock on this chip. Low multi and fsb wall are holding it back.


Also:

Celeron 440 3.5 GHz (used), 1.44 VCore, 350x10 Geminii cooler,
(or 340x10 1.400v small stock cooler).
Celeron 420 3120 MHz, stock cooler and Vcore (1.30). Hits fsb wall 391x8.

Nice HTPC with a Conroe Celeron and the Radeon XPress 1250 10 bit color HDMI Abit F-i90HD motherboard.

There shouldn't be a FSB wall on the MB. The E21x0 and E4xx0 chips will top out around 425MHz FSB. Try upping NB and SB by one notch. Also use 5-5-5-15-2T timing.
 
E2160 @ 3.2
400x8
1.4V in BIOS
EVGA 680i
2x1GB OCZ DDR2-800
Stock cooler

Ran Prime95 all night, if it's still running when I get home tonight I'll start reducing the voltage. Even at 1.40V set in the BIOS it's staying low 60's C so it's not terrible.

Not bad for a <$90 CPU.
