Xeon L5430 VT-x speedstep and ssse 4.1 - Page 4

post #31 of 75
Hi Vincent12 and Sparticle, thanks for your useful information, which coolers are you using? I have a stock core 2 duo cooler (the big one without the copper base *I think*) and I wanted to get a L5430 however I can't find a cheap one, neither on Ebay or Aliexpress, so I'm thinking maybe get the L5420 ($41) and overclock a little bit, on my motherboard with that cpu I should be able to overclock to 3.6 GHz unless of course the temperatures get too hot.

edit: I found a L5430 for $47.30

I use Arctic Cooling Freezer 7 Pro Rev 2 coolers in all my machines. They are awesome. In respect of OC I have no overclock potential with these CPU's on my motherboard it seems. I could overclock an E5500 and E8600 without any issues to 4.00 Ghz. But, the L5430 Xeon processor gives no OC potential on my board. All I can get is 333mhz x 8 which is the stock 2.66 Ghz for this processor.

Anything above 333 and the machine will not POST and reverts back to 2.66 Ghz.

Cheers

You can also overclock by increasing FSB, these P45 chipset motherboards are some of the best motherboards for FSB overclocking (remember I also have ep45-ud3lr). I was able to overclock my old 1.86 GHz Core 2 Duo up to 490 MHz FSB stable (3.43 GHz), I can help you with the settings if you are interested, I don't see why it shouldn't work for you as well. At 490 FSB your processor will run at 490*8 = 3.92 GHz.

This is strange, so you could actually get FSB stable to 400 MHz on the e8600? I wonder why it does not want to overclock your L5430? I cannot imagine that the problem lies with the processor. Have you tried increasing the cpu voltage?

Yes increasing the FSB rom the standard 200 to 266 and then using a higher multiplier (12-14) would get the Core 2 E5500 well into the 3+ Ghz range stable. And the max 10 x Multiplier. and 333 FSB would get the E8600 to standard 3.3Ghz.

On the L5430 it only has 6-8 x multiplier, so native at 2.66 @ 8 x 333. Cannot get FSB beyond 333 (which is really 333 x 4 or 1333) so sort of makes sense as this is a 1333 FSB motherboard. Without more multiplier no way forward.

Also this board is a G41 Chipset not P45. My next bet would be to look for a P45 board with a 1600 FSB then I should be able to get to 3.2 Ghz in thoery (400 x 4 for the 1600 FSB and 400 x 8 for the CPU) unless you know how to OC the L5430 and this board GA-G41MT-D3 with the limitations I outlined.

@snorbaard

I managed to get the system to POST with FSB 343 set and 8x for a theoretical 2.74 Ghz. Anything above and it will not POST! In Ubuntu the processor shows as stock 2.67 Ghz. So not worth anything at the OS level.

@sparticle

I didn't realize the e5500 had such a high multiplier I just made a wrong calculation and I got confused for a moment with Vincent12 who has a P45 motherboard which can go to 1600 FSB. I'm sorry to hear that you have trouble with the FSB wall, I don't think that chipset can go much higher than like you said 1333 FSB. Unfortunately I don't know if it will be worth it for you to get a secondhand P45 motherboard unless you can get one for really cheap, but then again I also read some more in the other thread and it seems the L series xeon chips aren't as good overclockers as the E and X series processors. sadsmiley.gif

My Gigabyte Board EP45T UD3LR has a setting with 400B and 400A.. I coulld try this.
Problem is that the Gigaybte Board with L5430 is running in our Router on the closet under the floor biggrin.gif

What about overclocking the L5430 in Asrock Board P43 Pro /USB3 with P43 Chipset?


My P5Q3 is running with a Q9550S CPU. Third L5430 functions as a spare part in second P5Q3<=(which got broken by itself).

400 MHz FSB is not an option because I use 16GB DDR3 -1333 Samsung memory.
Both dfferent Corsair RAM kits are unstable even without overclocking. Just one Corsair DIMM runs well

@snorbaard:
I have a Noctua NH-C12P SE14 CPU Cooler.
14cm fan and 14cm cooler height.

The company has a Mainboard compatibilty list for nearly every mainboard for this cooler at least.

(Might not fit in all cases with few space).
It has two Low Noise Adapters, which you easily place between Mainboard fan connector and cooler connector.
The blue throtteling adapter limits fan speed to 750-800 rpm. The Black Low Noise Adapter throttles to 900rpm.

The company is from Austria. But the The NH C12P-SE14 is quite expensive. 60 € (about 45 $)

Do you use the one as a router or is it just next to your router for something else?

If I recall correctly P43 chipset is similar to P45 and should be able to overclock quite a bit on the FSB. Also I think P5Q3 can also overclock? My motherboard has a lot of options to change the memory multiplier in order to lower the memory speed to keep it stable when you increase the FSB. I don't want to push you to overclock, I was merely curious how far a L5430 could go. If your FSB wall is at 450 FSB then you could theoretically get 3.6 GHz, but like I said, I am not sure if the L series Xeon chips can overclock well, even after reading the other thread. At least I know they will be nice and cool and energy efficient at stock speed.
