939 Athlon 3800+ x2 = Toledo or Manchester?

[phatboy]

when i run CPU-Z i cant choose between the first or second core, is there something i have to do in windows to activate dual core usage or nething ?

Cheers

In CPU-Z does it say 2 cores / 2 threads at the bottom? the latest version of CPU-Z doesn't let you chose the individual cores in the drop down box, but only if it is a dual processor system not dual core.

If it says you only have one core active then you need to update the ACPI HAL in the device manager and update driver if it currently says 'uni processor PC' you need to update the driver to make it into 'multi processor PC'.

Hope this helps.

just out of curiousity, what mem timings are people using to get the clocks that high?

Depends what divider you're on, for instance 300 x 10 on a 133 will have your RAM running @ 200MHz and obviously that's the stock speed for DDR400. If it were on a 166 divider, it'd be running @ 250MHz so you might have to loosen your timings to 3-3-3-8 or something and possibly up the vDimm, depends what your RAM is rated to run at in the first place though really.

guys

did i get lucky and pick up an older 1mb toledo?
or is it ment to be 2x1mb?

must say though i am impressed with this
2.8GHz on air with a Cooler Master Hyper TX cooler and a asrock board (max v core 1.4)
built this system as a freebie media centre for me old man but im a little bit envious lol

Toledo is the newer core and allegedly has an improved memory controller and the late 2006 onward cores are generally doing around 2.7-2.8GHz at stock volts and can scale up to 3GHz with up to 1.5v with only a few being less than 2.7GHz.

Kind of

Both Toledos and Manchesters were manufactured on E4 and E6 revision silicone. The E4 revision's memory controller handles overclocking better, but can't deal with 4 sticks of RAM at DDR400, and drops them all to DDR333. The E6 revision's memory controller doesn't overclock as well, but will take all 4 sticks of RAM at DDR400 without a problem.

Take the Opteron 180 for example. There were some E4 revisions of these and they were absolutely golden chips, hitting ~3.2Ghz on air. There weren't many though, most were E6 which still managed ~3.0Ghz. However, these were both Toledo cores (Denmarks if you want to be pedantic ) In short, the Manchester/Toledo designation has nothing to do with age/date of production. It is solely to do with how much L2 cache the chip had when it was produced (ie. before disabling any of the cache).

There is also the debate between the "true" Manchesters and the crippled Toledos. The true Manchesters were manufactured with 512kb L2 cache per core. But when the Toledo series came into production, instead of running two production lines, all chips were manufactured as Toledos (ie. 1mb L2 cache per core) and then some were disabled to make them Manchesters.

<maddness>, your CPU was manufactured a Toledo. Then half of the L2 cache on each core was disabled. So technically, it is a Manchester. CPU-Z picks it up as a Toledo because it was built as one.

ah well was getting excited there, i thought it was special lol

it was just that i saw some cpu-z shots showing just 512kb l2 cache
and this showing 2 x 512kb, maybe they were just older versions of cpu-z

still a bargin nevertheless at £25

If your memory is 2-3-3-6 1T then maybe try 2.5-3-3-7 or 2.5-3-3-6 1T.

Try 10x multi @ 275FSB at stock and if stability problems occur then knock it up to about 1.375v or 1.4v(or higher to about 1.5 - 1.55v max but watch temps). Try this on a 166 divider. If it doesn't work then maybe try a 150 divider or lower.

Once you fiddle about with it for a while on top of lots of reading you will understand it all much better. Post back if you make any advances.

You do have 2x512kb cache, that's the 512kb cache per core that the Manchester chips have.

You have 2x512kb L2 cache in total, ie. 512kb attached to each core.

A Toledo (screenshot from my 4400+ X2) will look like this:

What could I expect on my A8N-E?

I think going from a 3Ghz 4000+ to a 2.8Ghz 4200+ X2 might be a worthwhile bump for my 939 system...

'scuse the 'Hijack' por favor!

My A8N-E is fitted with a Venice 3800+ (single core) ATM.
I was considering an X2 4200+ due to good price/performance, but i wondered what i'd need to do...it cant be old one out, new one in, surely?!?

to be honest, going from single to dual core is that easy

all i did was take out the old chip, add new paste to my Freezer 64 and away i went

you have to make sure you system is selected as a "multi processor computer" in the system, but that is about it mate.

just make sure you set everything to stock in the BIOS just to be safe before you do the switch

after installing the chip download the AMD dual core optimiser, seems to speed things up a lil bit on certain apps

Good luck

you can check if it is set up as a multi cpu machine by going to:

Control panel > system > hardware > device manager. And then clicking on "computer" drop down, this should tell you what your system is set as. when i installed my Dual Core it automatically recognised the new chip and did it all for me, good idea to check just incase tho.

Athlon 64 dual 4200+ toledo 90nm hits 3Ghz 1.55v 42c max
fsb @280 *11 = 3080Ghz

1.8Ghz - 2.8Ghz 1.45v- 1.55v 90nm

Using an akasa Evo 120 bloody good performance 3 hi-capacity 8mm copper heatpipes and its quiet.

Ok my settings are:

HT 290
Multi 10
HTT multi 4 ( which means its going over 1000 but it cant work at 3 for me??)
Core voltage 1.365 in bios (motherboard overvolts to 1.39)
Memory divider 333mhz
Memory timings:
2.5
4
4
10
1T
DDR voltage 2.9 (crucial say to run the ram at 2.8-9 i run at 2.9just to be sure)

I think thats all the settings to need to know.

what mobo do you have? HTT 4 is quite high for 290 HT
