[MOD] LGA775 Support For LGA771 Xeon CPUs - Page 304

post #3031 of 12376
There are brand new 2x 2GB DDR2 800 Low Density modules available for less than 30 Euro at ebay.
I have bought myself.
The only drawback is that they are not CL5 but CL6. Still the system is fast even with CL6, if only you have 4GB or better 6GB.
Then again those CL6 rated modules run at 5-5-5-15 timings and pass the memtest86+ on my motherboard, so I run them at CL5

You should find all that you need in the first few posts of that thread.
The microcodes for the CPU are named after their CPUIDs. The program CPU-Z shows the CPU ID, it's a combination of "Family" "Model" and "Stepping".
So in the case for a E5462 it's 6, 7, 6. -> 676 (CPUID 10676)
Also it's easy to google it ... just try "xeon x5472 cpuid" - that will give you links for example to www.cpu-world.com and there you see the CPUID for that CPU (for the X5472 it is 1067A).
The Revision C0 or E0 is not important for the microcodes since that is just a minor enhancement to the production and sometimes some features are enabled, but the core model is the same.

So for all the Xeon 54xx models you should be fine using the 10676 and 1067A microcodes.
One thing I couldn't find out and nobody here answered me to that question is what the platform ID stands for. I guess it's the socket like LGA 775, 771, or BGA or some other form (mobile sockets, soldered directly to the board aso.)
In the example on how to mod the BIOS they use platform ID 4 and 40 for the 10676 CPUID and platform ID 44 for the 1067A CPUID. The strange thing is that most of the time when I look into a BIOS I see outdated microcodes for these CPUIDs in there with platform IDs 1 and 10 and 11.
So whenever I mod a BIOS I just add all these six patches (4, 40, 1 and 10 for CPUID 10676 and 44, 11 for 1067A). IF there is enough space in the BIOS (1MB often is too small). AND I delete the old onces since it may happen that the BIOS uses the first matching patch and that may be the old one.

Oh and keep in mind that the Xeon 54x2 CPUs already have a 400MHz FSB speed. So overclocking these CPUs won't get you far (because of the low multiplicator). To use it in a system at stock speed will be fine though (like when your mainboard doesn't support overclocking [adjusting the FSB] but is capable of 400MHz FSB)

Well this explained pretty much everything. Thank you very much, I was worried that once the mount the CPU it may prevent the system from booting, so I wanted a patched BIOS beforehand. Thank you again.

@Bucho
My MB is Rev 3.0 so I'm lucky with that. AHCI mode is present in BIOS. Well I don't have much money to spend so I'll try to find cheap RAM somewere. Maybe on Ebay or here in my country. I have LGA775 mobo with DDR3 slots at work but that thing is dead sadsmiley.gif
post #3034 of 12376
I`m in a little bit of a mind/cashe pinch................
I have on offer E5420, E5430(with the sticker) for 43euros, but there is guy, that is offering me L5420 (low voltage version) for 55-60euros(without the sticker) that are unused (even the guarantee sticker(or whatever it is) on the package is untouched..................................
Is the L5420 version worth the extra euros ?????????????????????????????
post #3035 of 12376
@patentman
30 EUR or less for a brand new pair of 2 x 2GB DDR2-800 RAM is fair, that's right. CL6 modules most of the time work with CL5 settings too like you said. I had to RMA a pair of Patriot 2 x 1GB DDR2-1066 CL5 RAM and they offered me 2 x 2GB DDR2-800 CL6 RAM for exchange which I accepted. They also run fine with CL5.

@Sosuke593
Most of the mainboards with latest official BIOS already have some microcodes for these CPUIDs in there. But most of the time they are outdated and so the CPU will work but may miss some features.
In the past 22+ years that I screw with and on (hehe) PCs the only mainboards I came across that refuse to post at all with unknown CPUs were OEM boards used in IBM, HP, Dell ... systems. Most of the regular brands like ASUS, GigaByte, MSI ... should at least post and even maybe boot and work without an issue.

@Communist
Great - so your board should at least run fine with stock 333MHz FSB. AHCI is also good since with that you may even attach SSDs and (with Win7 and up) benefit of it as much as SATA II speeds allow. With AHCI (and the regular Microsoft MSAHCI driver) you should have all features like TRIM, NCQ and access to SMART values of the SSD as well as correct alignment and great speed.
DDR3 prices went straight up since last year so you don't have to be sad about not having to buy DDR3. About a year ago a 8 GB ( 2 x 4GB) DDR3-1600 Kit was about 35 EUR here where I live. Now it's around 60 EUR - so it almost doubled!

@GIGAFUN
Depends on what you want to do with the CPUs?
Do you want to overclock them to the max? Then maybe the E5430 (or even better a E5450 or X5460/70) would be the best.
Do you want a moderate overclock at low voltage and heat? Then maybe all of them would be about the same.
Do you want to run them at stock and don't care about heat then any of them will be fine.
Do you want to run them at stock and have a low power/heat system or maybe even want to undervolt them then maybe that L5420 would be the best.

The L, E and X just state that the voltage at stock will be different. It does not necessarily mean that a L model because of it's low voltage at stock will gain high OC results with still low voltage.

Thats too expensive... Which country are you from? rolleyes.gif

Last I bought a x3353 for $16 from Canada and a e5462 for Euro 27 from Germany (both including international shipping)smile.gif

Also bought one e5410 for Euro 9.5 incl shipping (but that was lost in transit)mad.gif

Hello everybody smile.gif I'm new here and I'm reading this thread from the first message (I'm at the page 41 for now...) but it takes time to read all...I have a Maximus II Formula with a E8400, I heard about this mod just yesterday. I order this Xeon E5450 http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=161265871700&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 and the sticker http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=161260075294&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

1/ Do I need to flash the bios with a modded version ? I have the latest 2302 bios...

2/ Does anyone have a spec SLBBM ? Is it good ?

3/ Did I do a good choice to take the E5450 ? I don't want it warms too much, I thought with "just" TDP of 80W it will running well...I know it's a lottery rolleyes.gif

Sorry if my ask is already maybe answered in this thread...Thanks thumb.gif

I think you can get a 5460 for same price.
