Im coming from ddr1 so everything is very different.
This isn't directly selectable in BIOS. With most chipsets the setting is done automatically by the BIOS based on the current FSB. I don't know if anyone has started testing this. But the best way to find out how to manipulate it is to run memory bandwidth tests as you run up the FSB. jumping to the 1333 strap from 1066 will result in a hit to bandwidth and latency on the memory. I'm not sure but i also believe that everest will report the current strap.Quote:

all of them are compatible with 800MHz ram. by changing the reference frequency and memory frequency you are setting the divider. It's not the most user friendly method of setting this because it makes you do some math, but it works. Use the table in the post listed to set your divider, then do the math to figure out your true memory frequency.Quote:

Im not sure Im doing this right, I keep getting decimals.
for instance, say you want to run DDR2-800 with a FSB of 300. That would require a 3:4 divider on your memory. 300/(3/4)=400*2(because its ddr)=800Quote:

200 533 3/4
also any time you start dividing fractions, you will end up with a chance decimal. just round to the nearest whole #
Yeah i just figured that out... im an idiot =)

Sandra: Yes: You can run the benchmarks but if you try to read MB info, instant hang.
To recover from a vcore reset, you MUST remove all power from the MB. I.E. unplug or power off the PSU and wait for the green light on the MB to go out.
i cant figure this out. im using the latest bios and i cant hit 440FSB at maximum MCH/FSB voltages. it just doesnt POST or freezes at POST.
BUT im perfectly stable at 400FSB at minimum MCH/FSB voltages.
it seems like the vcore to the CPU is not changing after adjusting some extra vcore.
Did you just jump to 440 or did you work your way up to it? I did find that with this board more voltage isn't always a good thing. At several 400+ steps, lowering the voltage actually made things more stable.Quote:

I am now or more like in 3 days will be a proud BX2 owner anything I need to know? Haha just kidding I will read through the thread again but actually does anyone if super talent ram works fine with this mobo?

229.00 and great customer service.
That is the bulk version which I am pretty sure means OEM which is about the same at newegg for the OEM version and other places. I needed to go retail because I own 0 cords and will need them etc. Thanks for the site though.
get the OEM version and order some nicer cables. OEM cables look like crap.
Already picked up the board through newegg so I am set. Hoping Ram works with the board now.

I also found some of the ram timings not working as they should on 2333 so flashing back may give you some issues also.
If you have a 6800 you may want to try this.
Set 200 reference, set 533 for the ram (3:4) and 333fsb for the CPU. If you have good memory you should be able to set 4-4-3-8, TRAS dead low will actually hurt performance.
Now with the 6800 you will set a 12 multi for 4GHZ or 11 for 3.6+.
Access latency will be somewhere around 6ns faster in this config than running the ram 1:1 even if you are running well over 900 1:1 in 1067ref mode.
Im trying to source a 6800 to test here, im stuck with a 6700 so 10 multi is all i have but I have some data i can share.
Goldmem pro used for bandwidth, everest for latency.
CPU speed was manipulated with the strap to force given ram speeds, even though 4:5 267 REF at 888 had the highest bandwidth its access latency is no where near as good as 888 200REF, which will make the 200REF setting faster.Now I know the CPU would be faster at 355fsb but we are looking at the memory here not the final CPU speed.Code:memspeed FSB REF Strap ratio bandwidth latency
833 333 267 4:5 4736 61.4ns
833 311 200 3:4 4639 55ns
888 333 200 3:4 4965 51.5ns
888 355 267 4:5 5041 57.6ns
Remember C2D does not need tons of bandwidth, it just needs to use the bandwidth more efficiently. Lower access latency = more performance.

No X6800 here :(
I'll try tomorow with Q6600 and see if its working with 9+ multi
Can you give us the best settings for the 6600??? Please?? Thanx!!Quote:

ah, so the reference frequency is actual control over the chipset strap. I was originally under the impression that it was just a way to force dividers on the memory controller.
for all you e6600 users this doesn't really help you out. At lower strap settings the ultimate stable FSB is significantly lower. It boils down to you having to test things out for yourselves (i know you despise this). With the ability to control the chipset strap, you have to make the trade off between memory latency and CPU speed (FSB speed). Basically you will have to bench at your max FSB on each of the strap settings (200/266/333) and go with the one that gives you the best stable numbers for the application you are most interested in. As with anything there is no "best setting" for any given CPU, each is different and it all depends on what you are most concerned with.
Tony, how does the chipset strap influence stability of a given speed on your memory? for instance if you were to run on the 133 strap with a 1:3 divider at 166 fsb. That would put your memory at 1000. All the stress would be on the memory controler, not the CPU or the actual FSB. I'm only asking without testing myself because I have no video card ATM.
edit: and i'm probably answering my own question, but I'm guessing that at this low a FSB you are killing your bandwidth to the point where any gains in lower latency are completely overshadowed. But i'll be testing for myself as soon as I get my video card.
<3 EVGA step-up
Glad you found your board, but to set the record straight it is the boxed version, One way to tell besides the fact that they would have to list it as an OEM is the color of the sata connector at the bottom of the board, the boxed one the connector is red and not so on OEM.Quote:

what FSB were you trying to use on the 1066 strap?Quote:

Keep in mind this board is geared more towards high multiplyer CPUs and most likely the bulk of the BIOS departments efforts are going to be going towards improving timings and performance at sub400MHz FSB speeds where there is more then enough data bandwidth to feed the CPU and still hold tight latency. If you want to move 400+ on the FSB you will be using the 1333 strap, and I don't know how that got changed in newer BIOS revisions.Quote:

Intel are looking to add more tweaks into bios, I asked for latency tweaks away from strap so you may see a bios that allows tighter latency with the 1333 ram table,this would make the board killer IMO.
I see a 3 horse race now with 975 boards, Badaxe2 Vs Infinity 975 Vs Aw9D max, out the 3 boards here the Infinity clocks the best in 1067, the badaxe2 has fully working 1333 and is able to force the 800 strap as does the AW9D....All 3 are awesome IMO with just price splitting them apart ;)

just set a 13 multi and off you go.
4 gigs may need slacker timings, thats all. 4-4-4 maybe
thanks.
Tony, you suggested using Everest for latency check. Are you not getting the same Everest vcore re-setting in bios issue that everyone else seems to be?
im using an old build, one that does not crash my system.
you could also use sandra, but you will have to test to get your own base line figures.

why not use mbench for latency/bandwidth http://www.x86-secret.com/Download/mbench.zip ?
I wish I knew this before :( Bunch of posts were suggesting 975 for 6600 and up.Quote:

Probably the best way to work our your settings is to start on the 333 strap and move the FSB up until you are either above 400 or you have hit the wall on what your CPU can do. If you are above 400, stick with the 333 strap, if you are below, then move down to the 266 strap and look for stability at lower FSB speeds as i'm guessing there's something like a 20MHz gap in performance from a strap change (such as 380FSB on the 266 strap could be better performing then 400 on the 333 strap).
There is no "best setting" it all depends on what your individual CPU can do with the cooling you specifically have setup, and then finding the lowest timings on the chipset and memory that you can support at the FSB it takes to get that CPU speed.
You can use both everest and sandra to run the benchmarks, just don't try to read any sensor info. They give VERY different latency readings though. The RALPH machine in my sig gives a 47.2ns latency in Everest but a 62ns in Sandra.Quote:

It happens to me from time to time when I go beyond 3.2, so I sorta gave up for the time being and left it there. But then again I'm a n00b and didn't know any better... 1st time OC'er.
Great thread BTW... learned a lot here (long time reader...1st post)
I hear this was the same on the BX1 board also. above around 320. Well since it is stable after the reset thing, it just is darn annoying to have to do. Almost as annoying as the hard disk led light staying on solid if you disable the secondary stat (marvell) ports in bios. You would think that these would be two easy things for Intel to fix.Quote:

It's hard for me to test beyond a 402FSB because my Orthos blend stable speed with this chip is 3.6GHz. I can run a little over 3.7 for 3dmark06 and 3.8-3.9GHz on this board for Pi tests. My cooler really isn't up to handling the 1.6v I need for 3.8-3.9GHz and I need a full 1.65v with this chip for brief tests @ 4.0GHz. This board can't give that juice and I don't think this cooler would tame 1.65v and 4.0GHz anyway. On any board this chip starts to struggle beyond 3.7GHz.
If Intel ever makes the multi adjustment in their BIOS work for C2D on this board I'll try futher with lower multis. I will give them credit for BIOS updates, I love them with this board; click an .exe file and relax while it does the rest.
BTW I have to use the reset switch like xgman describes when setting a FSB @ 400+. Once I have saved and loaded windows at least once I no longer have the problem cold booting whatever FSB I have locked in. I only need to do the reset when I first make changes for whatever the reason.
I tried moving from a 402FSB down to 356 for 3.2 and had to use reset when making that change as well. After the change was made and one reset was done I had no problems rebooting or cold booting.
Shaminos guide is correct for vcore. That's where I'm reading it from and I've for a 503 board as well. I can get to it right between my wb and the retention bracket. It's dead center in the pic, around the 10:30 position on the wb.Quote:

Yeah, that's the one. Double to triple digit?? Yikes! Maybe there's some masking on the solder joint and it's not making contact and you're reading floating millivolts. You could try the other side of that choke but it'll probably be even worse because you're measuring it unfiltered. I don't know of another place that voltage appears, except the cpu socket of course.Quote:

Intel says the hdd light fix should be in a bios fix next week or shortly after.

I guess I'll have to get the lead out so to speak, again.

Okay I think I have successfully achieved a 1GHz overclock and with that I am satisfied. I was wondering if some of the experts here could look at my settings and screenshot and tell me if everything looks okay.
My settings are:
Memory -
Reference - Default
Memory Freq. - 533
Memory Voltage 1.88 (Manufacturer limit is 1.9)
CPU -
V-Core - 1.4
Enhanced Power slope - Enabled
FSB Voltage - 1.275
MCH Voltage - 1.55
specs of your system would be nice, what ram? what cooler? Vfsb looks a bit low, is that default value? You should monitor temp with coretemp, more accurate. 52c load temp gives you a bit of headroom to raise vcore to 1.45v and maybe reach 3.6?
Sorry my ram is CORSAIR XMS2 (2 x 1GB) DDR2 800 and Im using a Tuniq Tower 120. My FSB Voltage (1.275) is one notch above default. I downloaded Coretemp and it is showing about 3C less than TAT so I think i'll stick with TAT just to be safe. Also Coretemp is showing that my v-core is only 1.325 but its really 1.4. :confused:
I'm hardly an expert but I ran an overclock just like that except FSB @1.3 and CPU @default. I wish they had default settings in the bios for the FSB and MCH voltages though. Also my memory was @667.Quote:
