rpsgc is sort of correct. It's true the card won't downclock the ram at all (and the gpu less) if more than one monitor is attached. The reason for this afaik is that it is only possible to adjust memory clock during vblank, and since multiple monitors don't run synchronized it is impossible to get...

I have not heard any problems like that either. You don't need more 3D horsepower to set up a 2nd or 3rd display. Either you are doing something wrong or there is something wrong with your card. A monumental problem like that wont affect the whole 5000 series without everyone knowing about it. No w...

It might make a half-way decent myth/XBMC machine, running at very low power. But you can't output full hd resolution in digital form. You only get LVDS (limited to 1366x768) and VGA (limited to 2048x1536, note N450 has a limit of 1400x1050 instead), no dvi/hdmi. It is possible though for board man...

I've only seen two reviews on the 5770 vapor-x card so far, @ techgage and hexus. Neither provides audio testing, just a "sounds quiet to me" subjective test with their rather noisy setups. ht4u also did a review and they quite liked it: http://ht4u.net/reviews/2009/sapphire_radeon_hd5770_vapor_x/i...

Quite possible though again might take 2-3 months or so before non-reference cards appear after launch (I still haven't seen a single non-reference 57xx/58xx card, except different coolers and 512MB versions of the 5750, though even in this case I think it used the same pcb). Of course, just when I...

I wouldn't necessarily bet on low profile 56xx cards. We have low profile 4650 today, so im hoping :) Oh, wasn't aware these exist. I think though these appeared a lot later than the "normal" 4650, and they seem to be a bit rare still. So yes I guess you could be right 5650 might appear as low prof...

http://www.techpowerup.com/reviews/Powercolor/HD_5750_PCS/28.html low quality pcb? mosfet? vrm? Since only idle power draw is affected, I don't think so. Seems more likely to be a bios problem (either not downclocking memory or gpu to the levels other cards are doing, or not lowering gpu voltage to...

Still almost nothing is known about these cards (or the chips that power them). It is confirmed however (IIRC) these will also support Eyefinity (more than 2 displays) - AMD stated actually this feature was driven by notebook requirements (for instance you could have 2 internal displays and still 2 ...

Well GDDR5 memory interface with 128bit really is as fast as 256bit memory with gddr3. There are actually reviews out there which nicely use performance-per-watt graphs, you can see HD5750 scores high: http://www.techpowerup.com/reviews/Powercolor/HD_5750_PCS/31.html GT240 also does very well: http:...

Thanks. When a spec sheet says it "supports" displayport, does that mean it's merely capable of having it, or does it mean it actually has it? example: http://www.endpcnoise.com/cgi-bin/e/std/sku=MSI_9400GT_512MB.html Well in this example the section mentioning display port support is just copy & p...

Thanks. Is it the 5000 series cards that all feature displayport or do I have to look at the individual specs for each card in that series? Also, any NVidia based cards that are quiet and offer displayport? The chip would always support displayport for the whole series (in fact more than one) but c...

I've seen a test of a green 9600gt and 9800gt here: http://www.computerbase.de/artikel/hardware/grafikkarten/2009/kurztest_zotac_geforce_9600_gt_eco_9800_gt_eco/5/ Not sure if they fixed the bios so it actually downclocks at idle with the 9600gt, though probably other manufacturers aren't affected.....

Here an answer from Asrock supprt. Atom PDF datasheet Page 5 : http://download.intel.com/design/pro...hts/320528.pdf Atom CPU only has 32 address line. If CPU support memory remapping function, it needs 35 address line. And below datasheet shows he has change 35 line to 32. So, it won't support mem...

I don't quite agree that all these boards have "virtually identical performance, as the CPU and GPU are the same". The GSE runs the gma950 at less than half the clock of the desktop version last time I checked, which could definitely make a difference. Granted, since even the desktop version is alre...

Good review. Looks like a good solution for stock speed. The 5770 has some potential for OC'ing, though...especially on the memory clock to make up for the nerfed channel width. Probably need additional cooling for the VRM and memory. Well according to the comments, he didn't apply the supplied lit...

Do you mean the Sapphire Vapor-X 4890? Sapphire has lots of cards, they also have a Toxic 4890 with improved cooling, though this one is geared for overclocking and may not be as quiet. I've seen some quick noise results for the Vapor-X here, http://www.computerbase.de/artikel/hardware/grafikkarten/...

These guys here tested a AC L2 pro on the 5770: http://ht4u.net/reviews/2009/amd_radeon ... ac_l2_pro/
They seemed to like it, quiet, cool and cheap. Cooler will use 3 slots though in total.

Well the same argument came up in another thread, http://www.silentpcreview.com/forums/viewtopic.php?t=54314 so I'm not going to repost that here. But sufficient to say, the paragraph quoted by -TDO- is inconsistent as the amount of address pin numbers is (1) larger than what's needed for a 32bit me...

please fix this glaring bug... Lynnfield core is exactly the same as Bloomfield. Even the idea of it not having any L2 cache at all makes me ROTFL.

I hope we get some reviews. Unfortunately, a lot of times sites just like to review the fastest or the first of a new model so who knows if will get some or not. I think that's more of a problem of the cpu manufacturers rather than the review sites. The bigger sites all get review samples before la...

I don't know the exactly resource, but there has been a long discussion about this topic. The answer from a Intel technican was, the existing Atom Cpus can only adress 4 GB. So there will be no board with memory remapping or more then 4 GB. -TDO- I'd really need a source to be able to believe this....

About time I say! (seriously, the energy efficient A64 X2 are already gone what took AMD so long...) I wonder though if pricing will be similar to what we saw with A64 X2 (which would mean a 240e would probably cost about the same as the regular 250). btw those quad-core Propus seem to be really che...

is that X2 4400+ 65nm Brisbane? I'm not sure it would be impossible with stock heatsink, provided you have some minimal case airflow, you're willing to go down all the way to 1000Mhz and are additionally undervolting (to less than what CnQ would set at that frequency). TDP should be less than 20W in...

Note however that you almost certainly need the ATX12V connector which is used to power the cpu voltage regulation circuitry, so I hope your PSU has that. Right. I was thinking of solving this with a molex adapter. Shouldn't be any problems there, should it? As long as your picoPSU handles enough a...

That's strange. The newegg specifications indiates that it supports DDR2 800, as does the Zotac page . Maybe it has a custom bios? Well, the ddr2-667 limitation only seems to apply to some 7050 chipsets, so it's probably purely artificial and every board manufacturers has ignored it :-). Anyway, to...

The Intel Atom CPU (&Chipset) supports 64-bit instructions but not 64-bit memory addressing... All Intel Atom based notebooks/pc's/mainboards have this issue... So it's really an issue of the CPU and not the support of the mainboard. I am quite sure this is definitely untrue. N/Z series atom do not...

What exactly is the performance difference between dual-channel and single-channel? << 10% for most applications. This is usually true, though some versions of the 7050 chipset also only offically support ddr2-667 (though maybe bios allows you to "overclock" in which case this is a non-issue) which...

No, this works differently for Phenom /-derivatives. Since the memory controller of those runs at different (and fixed - well it's changeable but usually not dynamically) clock than core clock, you'd actually expect the memory clock to be dependent on this clock (all am3 cpus so far have NB clock of...

Looks like msi is also preparing a nforce 750a sli based AM3 board (that's again the same chip as 8300 / 780a but this time without the nforce200 companion chip but still SLI capable): http://www.msi.com/index.php?func=prodm ... od_no=1874

Well I've got a PDC E5200 and it won't overclock that well - but that's got more to do with the board being unable to change FSB strap, so I never really tested the cpu limits. All the CPUs I tested didn't have that problem as the board I used allowed a 1:1 memory divider. It's a asus p5ql-em. 2 me...
