Here is where I am at: I have an older ASRock 775DUAL-VSTA using the German 3.17a BIOS, 4 GB RAM (2 X 2) and a E5300 that was doing 3.34 GHz with a Vendetta 2 CPU cooler.

I wanted to try to get to 3.75 - 4.0 GHz, just for grinns, so I did the BSEL and the volt mod but I still saw just the std. voltage in CPU-Z but the FSB went to 1064.5 from 800!

Strange, I guess my thinking was off, 'caus I thought; ok, E5300 is 2.6 GHz or 800 / 4 = 200 fsb x 13 multiplier = 2.6 GHz so E5800 at 1066 = 1066 / 4 = 266 fsb x 16 multiplier = 4.2 GHz (if I'm lucky! thought I'd give it a try).

However, this is what I got; at 1066 my E5800 is at 266 FSb at only 3.45 GHz on the 1066 BUS????

CPU-Z and several others verify it and I cannot go over 266 by even 1 click or I crash.

Still great for this old board but thought I could do better (CPU is at a cool 30.0 deg. C)

could be lack of Vcore or other voltage for IOH or ICH causing crashes
dial back your OC

Ok, now I'm really confused! I just opened up SetFSB and low and behold, it says I'm at 4.2 GHz with my E5800????

So where am I really? I've had 2 BSOD's in the last 24hrs but I dialed my OC back to 3.2GHz according to CPUID-Z which is 4.2GHz in SetFSB and so far so good (was at 3.5 and 4.4 depending on who you believe?).

All I know is this thing has never been this fast and my CPU temp is up from 35C to 43C.

Video encoding has NEVER been this fast and even accessing web pages is very fast so who knows where I am really at!

Ideas please?

Well, everything was going great until I tried to "up-date" my Radeon drivers.

Once I did that, my system starrted to systematically take itself out!

First the sound card went, then my vido cards got flakey, etc. Any how, I was forced to reset my CMOS and BANG! Everything started back up but of course things had to be reset, reinstalled, etc., but, here is the strange part, I was no-longer at 1066! I was back at 800 even though the CPU trace was still in place?

Can any one tell me how a physical change on my CPU is no-longer "seen" by my mother board and can I get 1066 back or not?

Oh, one other question, maybe unrelated but is a 3Dmark score of 20,058 (after CPU mod) good, bad, what and how do I compare it (never did this before, so pardon me if dumb question), also, was 16,825 prior to CPU mod, now back to 16,825 after CMOS reset?

Did I screw up resetting my CMOS?

Finally, everything works!

I started from scratch, cleared the CMOS and re-flashed the BIOS using the 3.19a German BIOS.

Prior to that, I removed all boards and memory, reinstalled CPU with VID and BSEL mods, 1 stick of 2GHz DDR2 PC5300 memory, both video cards (HD4850 512mb in the PCI-e slot and my X1950 Pro 512mb in the AGP slot and nothing else.

Let it POST and did an F2, reset all required in BIOS and played with the multiplyer and FSB and BANG! 4.3GHz!

So far, have run; 3DMark06, FreshDiagnose, Belarc Advisor and setfsb, and Windows XP Pro all confirm 4.3GHz (CPUID CPU-Z can't seem to make up its mind?).

Next will be prime.95.exe tonight.

So, here are my system specs;

ASRock 775DUAL-VSTA mobo
3.19a BIOS
Intel E5800 Pentium Dual Core CPU w/ VID & BSEL mods
Vendetta 2 CPU cooler
active, fan powered NorthBridge cooler
passive added heat sinks to SouthBridge chip
2 X 2GB generic PC5300 RAM
Radeon HD4850 512MB PCI-e video card
Sapphire X1950 Pro 512MB AGP video card
Auzentech 7.1 XPlosion sound card
Turtle Beach Riviera sound card
NOTE: 2 sound cards, one for system and one for Internet TV system
generic 5 port USB2 card
Pinnacle Callisto 7.0 AV/DV capture card
2, 400GB WD SATA harddrives
Windows XP Pro with RAMDRIVE ("sees" and uses ALL 4GB RAM!)
OKIA 750W PS
3, Gateway 24" 1080p LED monitors + 36" LED for Internet TV

Sound system is a combination of;
Auzentech
DTT2500 Surround System and select "old school" 60's and 70's high-end stereo components, 500 "REAL" watts per channel Voice of the Theater, etc.,.

Any how, it all finally works! ME HAPPY CAMPER!

Out curiosity where did you get your bios? I have a 775 Dual Vsta myself.

I got it off of a German website but I do not believe it is still available.

If you would like, I can email both the 3.17a and 3.19a files to you. Be sure to view the READ ME files before flashing!

Will this mod work with an E8500 1333 to 1600 on a board that only supports 1333fsb?

my first post! \o/ yay!

I know that this is an old Thread, but i hope someone will reply. I'm upgrading my GPU from an old overly jury riged 9800gt to a 560ti or a 570 and I'm pretty sure that my Q6600 is going to bottleneck my rig when I overclock my GPU. I'm gonna throw an aftermarket heat-sink to my CPU and overclock it to help with that problem. Only other problem is that I have a Dell(-.-). Can't/Won't mod the Bios and the crappy PLL is untouchable with any program I have found.... so my only option left (that I have found) is to a modest biggrin.gif 1066to1333 BSEL mod on my quad-core 775. I couldn't find the exact mobo specs (damn shady Dell) but all the parts in my mobo seem to be able to accept the mod (I'm on a Dell Studio540 btw). I believe that everything will work out fine, but my only concern is if i will have to do the 1.4v VID mod. Here is some pics for specs on my junk.

Mobo.jpgCPU.jpgRam.jpgMemSample.jpg

Like I said before, I'm fairly sure that my rig will accept the 1066->1333, but I'd like to do this thing in one shot and only have to apply arctic silver once (>.>). Still, I'm really not sure if i will have to do the 1.4v mod/not sure if my rig will accept the 1.4v mod.

I'd like an opinion from someone who knows what they are doing before i do anything. I'm comfortable modding my GPU because if you fk up, you lose your GPU...mess up here...well.... =D

Thanks in advance. I love Overclock.net, so helpful for all my GPU needs...I just need a little advice when it comes to my processor. Any info is appreciated. :-)

Hey,

My stock BIOS won't allow BIOS-level overclocking (I use software instead), so I want to try one (or more) of these mods. I have a Pentium Dual-Core E5800 (not Core 2 Duo or whatever with the same model name), with a x16 multiplier.

Strangely, CPU-Z shows my voltage to be 1.392, though I never tried changing it from it's stock 1.3625 (according to the Intel website), not that that's possible anyhow. I don't know how it got that high, but it may turn out to be a benefit for me.

My motherboard only supports 800 MHz FSB, and I can overclock that to around 968-976 depending on environment conditions. I want to know if it will support a BSEL mod to 1066 MHz. Seeing as the system crashes when I get the FSB beyond 976, I would think not, but it may work if I use a VID mod too. I am not sure why it crashes - it may be the voltage on the CPU, maybe the motherboard, or maybe something else.

Any suggestions? I don't want to try this unless I'm sure it will work.

BTW, I have seen people who can't believe the E5800 can go beyond 3.5 GHz. I can easily get mine to 3.9+ GHZ with stock voltages and stock cooling just by changing just the FSB using software overclocking! My temps stay well below 70 C, but I haven't watched them for a while so I can't give further details (I'd guess around 50-60 C under load). I don't see why this is so unbelievable. I would probably get even higher speeds if it weren't for my motherboard (which I'm trying to fix now).

I search a way to underclock my E2180 from FSB 800 to FSB 533. The FSB is fixed at the Supermicro PDSME+ Bios.
Know everybody a way to underclock?
