Recommended Memory.

[Lazgoat]

Can anyone rate theseTwinmos Memeory modules?

PC3700 = TwinMOS chips
PC3200 = Mtec and TwinMOS chips

If not where can I get Twinmos/Winbond or any decent good value PC3200+ memory in the UK?
I hope this will solve my 166FSB issue that I'm having with my PC2700 Samsung RAM.
Any ideas?

Of all the memory I've used over the years (been using PC's since 1987) I've yet to find memory as fast as OCZ Technology's. I've owned their PC3200, PC3200 Rev.2, PC3500, EL-PC3500, and now use their EL-PC3700. They've recently moved production in-house, and are manufacturing their own product, just as Kingston does. A crucial (no pun intended) attribute of their memory is it's ability operate (even overclocked) at very low voltages (2.5V-2.63V), lower then any memory to-date. The first review I linked to below is from BlargOC, this is what they said pertaining to voltage in that review; "OCZ's closest competitor in terms of performance is GeIL, who claim to manufacture their own 4.5ns chips to put on their own PCBs, creating lightning quick true DDR433 ram. However, some say these chips are just re-badged 6ns Winbond or Samsung chips, that have been lapped down and re-stamped. This would make much more sense as their website states a 2.7v - 3.1v operating voltage, which is vastly greater than this OCZ memory; and it would also stop it from working correctly on my BD7-II motherboard. I'd love to test some of this sometime, as I am VERY skeptical of this (GeiL) memory. Voltage is indicative of quality IC's, just as it determines the quality of a good processor core. OCZ simply manufacturs some of the best (if not the) IC's available. One thing I will say about Twinmoss PC3700, is it's default voltage is 2.8V, and that is cause for healthy skepticism; http://www.deviantpc.com/coranto/Epu...LENHErai.shtml

Over a year ago, OCZ's reputation was detrimentally affected by the false accusations (planted in forums) of a few unscrupulous employee's. They literally tried to bring down the company, stealing physical and intellectual property from OCZ. All in hopes of starting their own memory company. People say plagerism is the highest form of flattery. I see it as immoral efforts of the weakminded, weak-willed, and these criminals are everything that's wrong with American busniess. What really frustrates me, is in a hobby replete with intellectuals, there's blatent ignorance among many enthusiasts. When they prejudge a product based upon "rumor", and "innuendo", (many overclockers do just that) they become idiot-savants (EDIT; just idiots). I've read so many forum threads stating; "nVidia sucks, ATI rules, because my friend told me so..." this is how a good portion of info is propagated on many forums. One reason I came to AOA, was due to the "moderation." Aedan and the other Moderators here, have an astute grasp of PC's, and keep the discussion technical. In fact I'm willing to bet a few Moderators here are either EE students, or professionals. I can't begin to tell you the conflicts I've had at some sites. I've been flamed (by the moderators) for suggesting an overclocker purchase a TTGI 450W or 520W PSU, over a 350W no-name. All because I didn't "ease" my way into the forum. I don't know about you, but I'd take information from a talking-Horse, if it were true, and accurate? They placed personality, before intellect. OK I'll step off the soapbox. I simply wanted to make a definitive statement about OCZ, because with their renewed success, past rumors have been brought up.

OCZ Technology has never rested on it's laurels, they design their way to the top. Corsair is quality, because they send quality buyers to memory manufacturers bidding on the best batches (stepping) for a given model, however; they don't make anything. OCZ Technology has taken a goodly portion of it's resources and re-invests it in R&D. This is why they were the first to begin matching modules for Dual Optimized, and others (Corsair's Twin-X) followed suit. They've recently shrunk the die-size on their memory, and introducing Quad-Band memory. My allegience isn't to the company for name;s sake, my allegiance is to whomever's stamping out the best IC's! I have 1GB of OCZ EL-PC3700 in each of my PC's, and being thorough in my research prior to purchase, is the hallmark of a good perfectionist! Here's some reviews; http://www.blargoc.co.uk/reviews/oczpc3500/page4.shtml

http://www.hexus.net/review.php?review=492&page=8 and here's a comment from the Hexus review of OCZ's EL-PC3500; "Our OCZ module allowed us to run at 217MHz at 2-7-2-2 (enhanced) with a small increase in voltage. The benchmarks certainly appreciated it...The benchmarks speak for themselves - there's nothing more that I can add, really. The fact that the OCZ EL-3500 module scoffed at 235MHz (470MHz DDR) at CAS2 shows that it's amongst the very best system memory you can buy."
Finally a store in the UK where you can purchase OCZ Technology DDR; http://www.pc-memory-upgrade.co.uk/

Wow, nice reply Liquid 3D. The reviews definately rate it as one of the best available, but look a the price tag! Eeeek!
Time to break into the piggy bank!

[Liquid3D]

Here's a much less costly alternative, and your original inquiry. Twinmos PC3700/DDR466 is only GBP 45.42 including VAT at Komplet, and GBP 38.66 excluding VAT; http://www.komplett.co.uk/k/ki.asp?a...pID=9&s=pl

Here's review; http://www.vr-zone.com/Home/news184/TwinMOS.htm

This guy is selling Twinmos.. both 256 and 512mb modules in both pc3200 and pc3700 speeds for decent prices.. and shipping to the uk for $5.00 extra priority mail.

I should be getting my 2 - 512 Pc3200s in soon

Can you provide a link?

[Nate-X]

dammit sorry lol here it is.. http://www.amdforums.com/showthread....5&pagenumber=1

It's 34 pages long atm and can't find the post about uk shipping but I saw it this morning so it's there somewhere

[bgcngm]

Hi

Do you know any website that ships not only to UK? I'm from Portugal and I wanted to buy two 512Mb sticks from http://www.komplett.co.uk/ but they only ship to UK or Ireland.

You forgot the A-DATA PC 3600 going out now....

The prewiew memory - PC3200 chip winbond BH-5- sure the best of the best.

Low price...240 and more Mhz...excelent timing...

I hope this one can be like the others.

Somone at Xtremesys just benched 3700MB/s with the A-Data. Your right about that. I asked where they purchased it from. i have to go find the thread, but they haven't replied yet, or it be in my mailbox. Any further and they would have the best bandwidth on the planet, as I beleive no one has breached 4K bandwidth yet. But anyway it was definately A-Data.

[Daysleeper]

Bad news...

The chip of the new A-Data PC3600 isn't the Windond chip but is A-Data.

The performance of this ram isn't really exciting, anyway...waiting.......for the new chip...

Ok, I had to lend a friend one of my Sammy PC2700 sticks as we suspected his was faulty.
Now I'm running a single stick of Sammy RAM single channle PC2700 DDR at 11x180 and its rock stable. However when there were two sticks runing Dual DDR I could not get past 166FSB in sync. I can run the two async (upto 210FSB so far)so long as I choose the right divider so the DDR Mhz does not go past 333Mhz.
Any ideas why I can get the two to work together past 166 FSB sync?

Thanks,

Laz.

[Liquid3D]

Perhaps the SPD on one is different from other? Even if their the same latency, model, voltage etc. there can still be differences amoung them. What I don't understand is, usually memory will run at the slower module's speed, but their able to reach 21FSB in Async, which then leads me to thinking ther's something amiss in the Dual Channel controller? Perahps the architecture is so radically different on the nForce2 that Async actually allows the memory to run at the higher 210FSB, instead of performance being pulled down to the lower speed?

Can someone explain to me how the divider can allow a 210FSB, yet keep the memory at DDR333? And I believe there-in lies the quandry.

[Lazgoat]

I've just checked in my BIOS and I'm running at 210x9 with the 5/4 divider, so my memory is at 336Mhz in the BIOS. In the POST screen however it shows up as 334Mhz. This is single channel Async and it seems stable. It was stable at 360Mhz sync anyway with one stick of memory.
Its likely the two memory modules cant work together in Dual DDR Sync out of spec (over 333Mhz FSB) as you suggested Liquid3D. I'll test the other one when I get it back next week.
In the mean time I'll see how high this single stick will go in sync.

Laz.

[Liquid3D]

I don't beleive you can run a single stick in "sync" the semantics of the term sync, implies there's another item to synchronize with? You can run it at 100%, and maybe the nForce2 doesn't discriminate between sync and 100%, but it's not technically running in "sync" it's just that in the BIOS sync also implies 100%.

[Lazgoat]

By sync I meant "by SPD". So as the FSB is increased the Memory speed increases as well. ie not using the dividers.
At the moment all I can get out of this single stick of Sammy PC2700 is 368Mhz. So I'm saving my pennies for something faster.

[Liquid3D]

Oh I get it. If you disable Serial Presence Detect, and still use the divider, to avoid overtaxing the RAM, you can change the timming on the memory to less aggressive latencies, i.e. 2.5-3-3-8. At these timmings, and increased VDIMM (2.7V - 2.9V) and you'll probably do much better. This is why the two modules didn't work well in sync (Dull DDR) because they tend to want to run at their own timmings, and the SPD can vary immensly between memories.
